Borderline Personality DisorderBPD Symptoms, Signs, Tips, and Treatment

What is borderline personality disorder (BPD)?

Borderline personality disorder (BPD) is a mental health condition that impacts how you think, feel, behave, and identify with other people—even yourself. If you have BPD, you probably feel like you’re on a rollercoaster, not just because of your unstable emotions or relationships, but also the wavering sense of who you are. Your self-image, goals, and even your likes and dislikes may change frequently in ways that feel confusing and unclear.

People with BPD tend to be extremely sensitive. Some describe it as like having an exposed nerve ending. Small things can trigger intense reactions. And once upset, you have trouble calming down. It’s easy to understand how this emotional volatility and inability to self-soothe leads to relationship turmoil and impulsive—even reckless—behavior.

When you’re in the throes of overwhelming emotions, you may be unable to think straight or stay grounded. You might say hurtful things or act out in dangerous or inappropriate ways that later make you feel guilty or ashamed. Having BPD can be a painful cycle that feels impossible to escape. But it’s not. There are effective treatments and coping skills for borderline personality disorder that can help you feel better and regain control of your thoughts, feelings, and actions.

Is BPD treatable?

In the past, many mental health professionals found it difficult to treat borderline personality disorder (BPD), so they came to the conclusion that there was little to be done. But we now know that BPD is treatable. In fact, the long-term prognosis for BPD is better than those for depression and bipolar disorder. However, it requires a specialized approach. The bottom line is that most people with BPD can and do get better—and they do so fairly rapidly with the right treatments and support.

Healing is a matter of breaking the dysfunctional patterns of thinking, feeling, and behaving that are causing you distress. It’s not easy to change lifelong habits. Choosing to pause, reflect, and then act in new ways will feel unnatural and uncomfortable at first. But with time you’ll form new habits that help you maintain your emotional balance and stay in control.

How to recognize borderline personality disorder

Do you identify with the following statements?

• I often feel “empty.”
• My emotions shift very quickly, and I often experience extreme sadness, anger, and anxiety.
• I’m constantly afraid that the people I care about will abandon me or leave me.
• I would describe most of my romantic relationships as intense, but unstable.
• The way I feel about the people in my life can dramatically change from one moment to the next—and I don’t always understand why.
• I often do things that I know are dangerous or unhealthy, such as driving recklessly, having unsafe sex, binge drinking, using drugs, or going on spending sprees.
• I’ve attempted to hurt myself, engaged in self-harm behaviors such as cutting, or threatened suicide.
• When I’m feeling insecure in a relationship, I tend to lash out or make impulsive gestures to keep the other person close.

If you identify with several of the statements, you may suffer from BPD, a cluster B personality disorder. Of course, you need a mental health professional to make an official diagnosis, as BPD can be easily confused with other issues.

What are the signs and symptoms of borderline personality disorder (BPD)?

Borderline personality disorder manifests in many different ways, but for the purposes of diagnosis, mental health professionals group the symptoms into nine major categories. In order to be diagnosed with BPD, you must show signs of at least five of these nine symptoms. Furthermore, the symptoms must be long-standing (usually beginning in adolescence) and impact many areas of your life.

The 9 traits of BPD

1. Fear of abandonment. People with BPD are often terrified of being abandoned or left alone. Even something as innocuous as a loved one arriving home late from work or going away for the weekend may trigger intense fear. This can prompt frantic efforts to keep the other person close. You may beg, cling, start fights, track your loved one’s movements, or even physically block the person from leaving. Unfortunately, this behavior tends to have the opposite effect—driving others away.
2. Unstable relationships. People with BPD tend to have relationships that are intense and short-lived. You may fall in love quickly, believing that each new person is the one who will make you feel whole, only to be quickly disappointed. Your relationships either seem perfect or horrible, without any middle ground. Your lovers, friends, or family members may feel like they have emotional whiplash as a result of your rapid swings from idealization to devaluation, anger, and hate.
3. Unclear or shifting self-image. When you have BPD, your sense of self is typically unstable. Sometimes you may feel good about yourself, but other times you hate yourself, or even view yourself as evil. You probably don’t have a clear idea of who you are or what you want in life. As a result, you may frequently change jobs, friends, lovers, religion, values, goals, or even sexual identity.
4. Impulsive, self-destructive behaviors. If you have BPD, you may engage in harmful, sensation-seeking behaviors, especially when you’re upset. You may impulsively spend money you can’t afford, binge eat, drive recklessly, shoplift, engage in risky sex, or overdo it with drugs or alcohol. These risky behaviors may help you feel better in the moment, but they hurt you and those around you over the long-term.
5. Self-harm. Suicidal behavior and deliberate self-harm is common in people with BPD. Suicidal behavior includes thinking about suicide, making suicidal gestures or threats, or actually carrying out a suicide attempt. Self-harm encompasses all other attempts to hurt yourself without suicidal intent. Common forms of self-harm include cutting and burning.
6. Extreme emotional swings. Unstable emotions and moods are common with BPD. One moment, you may feel happy, and the next, despondent. Little things that other people brush off can send you into an emotional tailspin. These abrupt mood swings—known as “affective instability”—are intense, but they tend to pass fairly quickly (unlike the emotional swings of depression or bipolar disorder), usually lasting just a few minutes or hours.
7. Chronic feelings of emptiness. People with BPD often talk about feeling empty, as if there’s a hole or a void inside them. At the extreme, you may feel as if you’re “nothing” or “nobody.” This feeling is uncomfortable, so you may try to fill the void with things like drugs, food, or sex. But nothing feels truly satisfying.
8. Explosive anger. If you have BPD, you may struggle with intense anger and a short temper. You may also have trouble controlling yourself once the fuse is lit—yelling, throwing things, or becoming completely consumed by rage. It’s important to note that this anger isn’t always directed outwards. You may spend a lot of time feeling angry at yourself.
9. Feeling suspicious or out of touch with reality. People with BPD often struggle with paranoia or suspicious thoughts about others’ motives. When under stress, you may even lose touch with reality—an experience known as dissociation. You may feel foggy, spaced out, or as if you’re outside your own body.

Common co-occurring disorders

Borderline personality disorder is rarely diagnosed on its own. Common co-occurring disorders include:

• Depression or bipolar disorder
• Substance use disorder (abuse of alcohol or drugs)
• Eating disorders
• Anxiety disorders

When BPD is successfully treated, the other disorders often improve, too. But the reverse isn’t always true. For example, you may successfully treat symptoms of depression and still struggle with BPD.

How long do BPD episodes last?

When you have BPD, you’ll likely go through periods of calm broken up by episodes when your symptoms flare-up. A trigger such as criticism, rejection, or overwhelming stress could result in an episode of intense mood swings, depression, impulsive behavior, self-harming, dissociation, or splitting, where you view things as either all good or all bad, with no middle ground. These episodes usually last from a few hours to a few days, but can last longer, depending on the trigger and the severity of your symptoms.

What causes borderline personality disorder (BPD)?

Most mental health professionals believe that borderline personality disorder is caused by a combination of inherited or internal biological factors and external environmental factors. Symptoms usually first appear in the teen years and tend to be more severe in young adulthood.

Is BPD genetic?

While the exact causes of BPD aren’t fully known, genetic factors may play a role.

• Studies have indicated that you have an elevated risk of developing borderline personality disorder if you have a family history of BPD, especially in close family, such as your parents or siblings.
• Women are diagnosed with BPD more often than men, but the reasons for that are not clear.

In addition to genetics, environmental factors may also increase your risk of developing borderline personality disorder. These factors could include:

• Childhood trauma, abuse, or neglect.
• Abandonment by a parent or an otherwise disrupted home life.
• Interrupted bonding as an infant, resulting in insecure attachment.

Studies have also shown that there are brain differences in people with BPD.

Brain differences

There are many complex things happening in the BPD brain, and researchers are still untangling what it all means. But in essence, if you have BPD, your brain is on high alert. Things feel more scary and stressful to you than they do to other people. Your fight-or-flight switch is easily tripped, and once it’s on, it hijacks your rational brain, triggering primitive survival instincts that aren’t always appropriate to the situation at hand.

This may make it sound as if there’s nothing you can do. After all, what can you do if your brain is different? But the truth is that you can change your brain. Every time you practice a new coping response or self-soothing technique you are creating new neural pathways. Some treatments, such as mindfulness meditation, can even grow your brain matter. And the more you practice, the stronger and more automatic these pathways will become. So don’t give up! With time and dedication, you can change the way you think, feel, and act.

Personality disorders and stigma

When psychologists talk about “personality,” they’re referring to the patterns of thinking, feeling, and behaving that make each of us unique. No one acts exactly the same all the time, but we do tend to interact and engage with the world in fairly consistent ways. This is why people are often described as “shy,” “outgoing,” “meticulous,” “fun-loving,” and so on. These are elements of personality.

Because personality is so intrinsically connected to identity, the term “personality disorder” might leave you feeling like there’s something fundamentally wrong with who you are. But a personality disorder is not a character judgment. In clinical terms, “personality disorder” means that your pattern of relating to the world is significantly different from the norm. (In other words, you don’t act in ways that most people expect). This causes consistent problems for you in many areas of your life, such as your relationships, career, and your feelings about yourself and others. But most importantly, these patterns can be changed!

How to cope with BPD: 3 self-help tips

1. Calm the emotional storm.
2. Learn to control impulsivity and tolerate distress.
3. Improve your interpersonal skills.

Tip 1: Calm the emotional storm

As someone with BPD, you’ve probably spent a lot of time fighting your impulses and emotions, so acceptance can be a tough thing to wrap your mind around. But accepting your emotions doesn’t mean approving of them or resigning yourself to suffering. All it means is that you stop trying to fight, avoid, suppress, or deny what you’re feeling. Giving yourself permission to have these feelings can take away a lot of their power.

Try to simply experience your feelings without judgment or criticism. Let go of the past and the future and focus exclusively on the present moment. Mindfulness techniques can be very effective in this regard.

• Start by observing your emotions, as if from the outside.
• Watch as they come and go (it may help to think of them as waves).
• Focus on the physical sensations that accompany your emotions.
• Tell yourself that you accept what you’re feeling right now.
• Remind yourself that just because you’re feeling something doesn’t mean it’s reality.

Do something that stimulates one or more of your senses

Engaging your senses is one of the quickest and easiest ways to quickly self-soothe. You will need to experiment to find out which sensory-based stimulation works best for you. You’ll also need different strategies for different moods. What may help when you’re angry or agitated is very different from what may help when you’re numb or depressed. Here are some ideas to get started:

Touch. If you’re not “feeling” enough, try running cold or hot (but not scalding hot) water over your hands; hold a piece of ice; or grip an object or the edge of a piece of furniture as tightly as you can. If you’re feeling too much, and need to calm down, try taking a hot bath or shower; snuggling under the bed covers, or cuddling with a pet.

Taste. If you’re feeling empty and numb, try sucking on strong-flavored mints or candies, or slowly eat something with an intense flavor, such as salt-and-vinegar chips. If you want to calm down, try something soothing such as hot tea or soup.

Smell. Light a candle, smell the flowers, try aromatherapy, spritz your favorite perfume, or whip up something in the kitchen that smells good. You may find that you respond best to strong smells, such as citrus, spices, and incense.

Sight. Focus on an image that captures your attention. This can be something in your immediate environment (a great view, a beautiful flower arrangement, a favorite painting or photo) or something in your imagination that you visualize.

Sound. Try listening to loud music, ringing a buzzer, or blowing a whistle when you need a jolt. To calm down, turn on soothing music or listen to the soothing sounds of nature, such as wind, birds, or the ocean. A sound machine works well if you can’t hear the real thing.

Reduce your emotional vulnerability

You’re more likely to experience negative emotions when you’re run down and under stress. That’s why it’s very important to take care of your physical and mental well-being.

Take care of yourself by:

• Avoid mood-altering drugs.
• Eating a balanced, nutritious diet.
• Getting plenty of quality sleep.
• Exercising regularly.
• Minimizing stress.
• Practicing relaxation techniques.

Tip 2: Control impulsivity and tolerate distress

The calming techniques discussed above can help you relax when you’re starting to become derailed by stress. But what do you do when you’re feeling overwhelmed by difficult feelings? This is where the impulsivity of borderline personality disorder (BPD) comes in. In the heat of the moment, you’re so desperate for relief that you’ll do anything, including things you know you shouldn’t—such as cutting, reckless sex, dangerous driving, and binge drinking. It may even feel like you don’t have a choice.

Moving from being out of control of your behavior to being in control

It’s important to recognize that these impulsive behaviors serve a purpose. They’re coping mechanisms for dealing with distress. They make you feel better, even if just for a brief moment. But the long-term costs are extremely high.

Regaining control of your behavior starts with learning to tolerate distress. It’s the key to changing the destructive patterns of BPD. The ability to tolerate distress will help you press pause when you have the urge to act out. Instead of reacting to difficult emotions with self-destructive behaviors, you will learn to ride them out while remaining in control of the experience.

For a step-by-step, self-guided program that will teach you how to ride the “wild horse” of overwhelming feelings, check out our free Emotional Intelligence Toolkit. The toolkit teaches you how to:

• Get in touch with your emotions.
• Live with emotional intensity.
• Manage unpleasant or threatening feelings.
• Stay calm and focused even in upsetting situations.

The toolkit will teach you how to tolerate distress, but it doesn’t stop there. It will also teach you how to move from being emotionally shut down to experiencing your emotions fully. This allows you to experience the full range of positive emotions such as joy, peace, and fulfillment that are also cut off when you attempt to avoid negative feelings.

A grounding exercise to help you pause and regain control

Once the fight-or-flight response is triggered, there is no way to “think yourself” calm. Instead of focusing on your thoughts, focus on what you’re feeling in your body. The following grounding exercise is a simple, quick way to put the brakes on impulsivity, calm down, and regain control. It can make a big difference in just a few short minutes.

Find a quiet spot and sit in a comfortable position.

Focus on what you’re experiencing in your body. Feel the surface you’re sitting on. Feel your feet on the floor. Feel your hands in your lap.

Concentrate on your breathing, taking slow, deep breaths. Breathe in slowly. Pause for a count of three. Then slowly breathe out, once more pausing for a count of three. Continue to do this for several minutes.

In case of emergency, distract yourself

If your attempts to calm down aren’t working and you’re starting to feel overwhelmed by destructive urges, distracting yourself may help. All you need is something to capture your focus long enough for the negative impulse to go away. Anything that draws your attention can work, but distraction is most effective when the activity is also soothing. In addition to the sensory-based strategies mentioned previously, here are some things you might try:

Watch TV. Choose something that’s the opposite of what you’re feeling: a comedy, if you’re feeling sad, or something relaxing if you’re angry or agitated.

Do something you enjoy that keeps you busy. This could be anything: gardening, painting, playing an instrument, knitting, reading a book, playing a computer game, or doing a Sudoku or word puzzle.

Throw yourself into work. You can also distract yourself with chores and errands: cleaning your house, doing yard work, going grocery shopping, grooming your pet, or doing the laundry.

Get active. Vigorous exercise is a healthy way to get your adrenaline pumping and let off steam. If you’re feeling stressed, you may want to try more relaxing activities such as yoga or a walk around your neighborhood.

Call a friend. Talking to someone you trust can be a quick and highly effective way to distract yourself, feel better, and gain some perspective.

Tip 3: Improve your interpersonal skills

If you have borderline personality disorder, you’ve probably struggled with maintaining stable, satisfying interpersonal relationships with lovers, co-workers, and friends. This is because you have trouble stepping back and seeing things from other people’s perspective. You tend to misread the thoughts and feelings of others, misunderstand how others see you, and overlook how they’re affected by your behavior. It’s not that you don’t care, but when it comes to other people, you have a big blind spot. Recognizing your interpersonal blind spot is the first step. When you stop blaming others, you can start taking steps to improve your relationships and your social skills.

Check your assumptions

When you’re derailed by stress and negativity, as people with BPD often are, it’s easy to misread the intentions of others. If you’re aware of this tendency, check your assumptions. Remember, you’re not a mind reader! Instead of jumping to (usually negative) conclusions, consider alternative motivations. As an example, let’s say that your partner was abrupt with you on the phone and now you’re feeling insecure and afraid they’ve lost interest in you. Before you act on those feelings:

Stop to consider the different possibilities. Maybe your partner is under pressure at work. Maybe he’s having a stressful day. Maybe he hasn’t had his coffee yet. There are many alternative explanations for his behavior.

Ask the person to clarify their intentions. One of the simplest ways to check your assumptions is to ask the other person what they’re thinking or feeling. Double check what they meant by their words or actions. Instead of asking in an accusatory manner, try a softer approach: “I could be wrong, but it feels like…” or “Maybe I’m being overly sensitive, but I get the sense that…“

Put a stop to projection

Do you have a tendency to take your negative feelings and project them on to other people? Do you lash out at others when you’re feeling bad about yourself? Does feedback or constructive criticism feel like a personal attack? If so, you may have a problem with projection.

To fight projection, you’ll need to learn to apply the brakes—just like you did to curb your impulsive behaviors. Tune in to your emotions and the physical sensations in your body. Take note of signs of stress, such as rapid heart rate, muscle tension, sweating, nausea, or light-headedness. When you’re feeling this way, you’re likely to go on the attack and say something you’ll regret later. Pause and take a few slow deep breaths. Then ask yourself the following three questions:

1. Am I upset with myself?
2. Am I feeling ashamed or afraid?
3. Am I worried about being abandoned?

If the answer is yes, take a conversation break. Tell the other person that you’re feeling emotional and would like some time to think before discussing things further.

Take responsibility for your role

Finally, it’s important to take responsibility for the role you play in your relationships. Ask yourself how your actions might contribute to problems. How do your words and behaviors make your loved ones feel? Are you falling into the trap of seeing the other person as either all good or all bad? As you make an effort to put yourself in other people’s shoes, give them the benefit of the doubt, and reduce your defensiveness, you’ll start to notice a difference in the quality of your relationships.

Borderline personality disorder (BPD) treatment options

If you think that you may be suffering from BPD, it’s best to seek professional help, ideally from a mental health professional with experience diagnosing and treating BPD.

The importance of finding the right therapist

The support and guidance of a qualified therapist can make a huge difference in BPD treatment and recovery. In-person or online therapy can serve as a safe space where you can start working through your relationship and trust issues and “try on” new coping techniques for dealing with the emotional pain.

An experienced professional will be familiar with BPD therapies such as dialectical behavior therapy (DBT) and schema-focused therapy. But while these therapies have proven to be helpful, it’s not always necessary to follow a specific treatment approach. Many experts believe that weekly therapy involving education about the disorder, family support, and social and emotional skills training can treat most BPD cases.

It’s important to take the time to find a therapist you feel safe with—someone who seems to get you and makes you feel accepted and understood. Take your time finding the right person. But once you do, make a commitment to therapy.

You may start out thinking that your therapist is going to be your savior, only to become disillusioned and feel like they have nothing to offer. Remember that these swings from idealization to demonization are a symptom of BPD. Try to stick it out with your therapist and allow the relationship to grow. And keep in mind that change, by its very nature, is uncomfortable. If you don’t ever feel uncomfortable in therapy, you’re probably not progressing.

Don’t count on a medication cure

Although many people with BPD take medication, the fact is that there is very little research showing that it is helpful. What’s more, in the U.S., the Food and Drug Administration (FDA) has not approved any medications for the treatment of BPD. This doesn’t mean that medication is never helpful—especially if you suffer from co-occurring problems such as depression or anxiety—but it is not a cure for BPD itself.

When it comes to BPD, therapy is much more effective. You just have to give it time. However, your doctor may consider medication if:

• You have been diagnosed with both BPD and depression or bipolar disorder.
• You suffer from panic attacks or severe anxiety.
• You begin hallucinating or having bizarre, paranoid thoughts.
• You are feeling suicidal or at risk of hurting yourself or others.

When a family member has BPD

Having a family member or loved one with borderline personality disorder can feel like being on an emotional roller coaster. You may be constantly on edge waiting for their next mood swing, emotional outburst, or irrational act to throw you off balance. Their destructive and hurtful behaviors are enough to leave anyone feeling abused and helpless. However, you’re not totally powerless in the face of your loved one’s symptoms.

The first thing to remember is that your loved one’s distressing or manipulative behavior is a result of their deep emotional pain, not a reflection of you. Secondly, your support can make a huge difference in their recovery.

Even if the person with BPD isn’t willing to seek treatment, there are ways to bring more stability to your relationship through improved communication, firmer boundaries, and changing your own reactions. To learn how to manage BPD in a relationship, read Dealing with BPD in Relationships.
