Understanding Borderline Personality Disorder
What it is and is not, and how it feels
If you've ever felt like your emotions are simply too much — too intense, too fast, too overwhelming — you are not alone, and there is nothing fundamentally wrong with who you are. Borderline personality disorder (BPD) is a recognized mental health condition that affects how you experience emotions, how you see yourself, and how you connect with the people around you. It is one of the most common personality disorders, and it is also one of the most misunderstood.
Many people living with BPD have spent years wondering why life feels so much harder for them than it seems to be for others. If that sounds familiar, this page is for you. Our hope is to help you make sense of what you've been going through — and to let you know that effective help exists.
What Is Borderline Personality Disorder?
BPD is a mental health condition characterized by three core areas of difficulty:
Intense and rapidly shifting emotions
Unstable or unclear sense of identity
Recurring problems in relationships.
These aren't occasional bad days. For people with BPD, these experiences form a persistent pattern that often begins during adolescence and can touch nearly every area of life.
The condition affects roughly 1–3% of the general population, and it shows up across all genders, backgrounds, and walks of life. In clinical settings, it is even more common — many people seeking mental health support are living with BPD, whether they know it or not. BPD frequently occurs alongside other conditions such as depression, anxiety, PTSD, ADHD, and substance use, which can make it harder to recognize.
BPD typically develops through a combination of biological sensitivity and life experiences. Research suggests that some people are born with a greater emotional responsiveness — feelings hit harder and last longer. When that sensitivity meets difficult life circumstances such as invalidation, neglect, bullying, or trauma, the result can be a pattern of emotional and relational struggles that crystallizes into BPD. This is not a character flaw. It is the outcome of real biological and environmental factors working together.
How BPD Can Show Up in Your Life
BPD looks different for everyone, but there are common threads. You may recognize yourself in some of these experiences — perhaps not all, and that's okay. What matters is the overall pattern.
Emotions That Feel Unmanageable
Your emotional reactions may feel disproportionate to the situation, or they may shift so quickly that you can barely keep up. Moments of intense sadness, anger, or anxiety may seem to come out of nowhere, and once they arrive, they can feel impossible to turn down. You might find that stress triggers episodes of feeling disconnected from yourself or from reality — as though you're watching your life from the outside.
A Painful Sense of Emptiness or Not Knowing Who You Are
You may struggle with a chronic feeling of emptiness — a hollowness that doesn't go away even when things are going well. Your sense of who you are may shift depending on who you're with or how you're feeling, leaving you uncertain about your own values, goals, or preferences. Self-esteem can be deeply negative and highly unstable, swinging from harsh self-criticism to brief moments of confidence and back again.
Relationships That Feel Like a Rollercoaster
You may find yourself pulled between an intense need for closeness and a deep fear of being hurt or abandoned. Relationships can feel all-or-nothing — someone is either wonderful or terrible, and the switch can happen quickly. You might go to great lengths to avoid being left, or you might push people away before they can leave you. Trust may feel like something you desperately want but can never quite hold onto.
Impulsive Behaviors You Regret
When emotional pain becomes overwhelming, you may turn to impulsive behaviors to cope — spending sprees, risky driving, substance use, binge eating, or other actions that provide momentary relief but lead to regret. These behaviors aren't signs of weakness. They are often the only strategies that seem to work in the moment, even when you know they come at a cost.
Self-Harm or Thoughts of Suicide
For many people with BPD, self-harm serves a specific function: it can feel like the only way to release unbearable emotional pressure or to interrupt a terrifying sense of numbness. Thoughts of suicide may be frequent visitors, sometimes chronic. These experiences deserve compassionate, nonjudgmental attention — they are symptoms of a treatable condition, not evidence that you are beyond help.
Anger That Surprises You
You may experience sudden, intense anger that feels out of your control — directed at others, at yourself, or at situations that might seem minor to someone else. Afterward, you may feel deep shame about these outbursts. This pattern can strain relationships and leave you feeling isolated, as though no one could accept the full range of who you are.
If several of these descriptions resonate with you, it does not mean something is "wrong" with you as a person. It means your brain and your nervous system have been working very hard to manage very real pain — and that there are more effective ways to find relief.
What Many People Don't Realize About BPD
BPD has carried significant stigma for decades, and many people who live with it have encountered dismissive or hurtful attitudes — sometimes even from healthcare providers. Here are a few things worth knowing:
Receiving a BPD diagnosis is often a relief rather than a blow. When you've spent years confused by your own reactions and behaviors, learning that there is a coherent explanation — a recognized pattern with known causes — can feel validating. It doesn't define you, but it can help you understand yourself.
BPD is not a life sentence. Research shows that a majority of people with BPD experience significant improvement over time, with studies finding diagnostic remission rates around 60%. People who are younger when they begin treatment tend to see especially strong outcomes. The sooner you seek support, the more room there is for meaningful change.
You Deserve to Be Understood
Living with BPD can feel profoundly lonely. You may have been told you're "too much" or "too sensitive." You may have watched relationships fall apart and blamed yourself entirely. You may have tried to explain what you're going through and felt that no one truly understood.

Frequently Asked Questions
Who do you treat?
DBT Center of Tacoma treats adolescents (13+) and adults who live in Washington state. We provide in-person services in Ruston, WA and telehealth across Washington state.
I think I might have BPD — how do I get a diagnosis?
A BPD diagnosis is made by a qualified mental health professional — typically a psychiatrist, psychologist, or licensed clinical therapist — through a thorough clinical interview. Our providers are all experts at assessing for a range of psychiatric diagnoses, included BPD.
There is no blood test or brain scan for BPD; instead, your provider will talk with you about your emotional experiences, relationships, sense of self, and behavioral patterns over time. Semi-structured interviews and self-report questionnaires can help support the diagnostic process.
If you recognize yourself in the experiences described on this page, that recognition is a meaningful starting point. Many people describe the moment of diagnosis as a relief — finally having a name for what they've been going through, and learning that it's a recognized condition with effective treatments. You don't need to be in crisis to seek an evaluation. You can begin by reaching out to a therapist who has experience with personality disorders and asking about an assessment.
How is BPD different from bipolar disorder or depression?
This is one of the most common sources of confusion, and misdiagnosis happens frequently. In bipolar disorder, mood episodes — mania or depression — tend to last for weeks or months and often occur independently of what's happening in your life. In BPD, emotional shifts are typically faster (hours or days, rather than weeks), more closely tied to interpersonal events, and more reactive to what's happening around you. A perceived slight from a friend might send you into intense despair that lifts hours later — that pattern is much more characteristic of BPD than bipolar disorder. It's also worth noting that BPD can co-occur with bipolar disorder, depression, PTSD, and ADHD, so having one doesn't rule out the other. Our providers assess for all of these common co-occurring problems and can talk with you about which diagnoses may be the most accurate fit for you.
Is BPD my fault? Did I do something to cause this?
No — and this is one of the most important things we can say. BPD is not the result of a personal failing, a lack of willpower, or a choice you made. Research shows that BPD develops through a combination of biological factors — including a heightened sensitivity to emotions that appears to be partly inherited — and environmental experiences such as childhood invalidation, neglect, or trauma. These factors interact during critical developmental periods, particularly adolescence. You did not choose to be more emotionally sensitive, and you did not choose the circumstances that shaped your early life. What you can choose now is to seek help, and that choice takes real courage.
Can BPD be cured, or will I always struggle with this?
The outlook for BPD is much more hopeful than most people realize. While clinicians don't typically use the word "cured,” the reality is that the majority of people with BPD get significantly better and may no longer meet criteria for the disorder. Studies following people over time have found that around 60% achieve diagnostic remission — meaning they no longer meet the criteria for BPD. Some research tracking longer periods has found remission rates as high as 86% over several years. Symptoms tend to peak in late adolescence and early adulthood and naturally decrease with age, and this process is accelerated by effective treatment. Recovery doesn't mean perfection — it means that the emotional storms become less frequent, less intense, and far more manageable. Many people with BPD go on to build stable relationships, fulfilling careers, and lives that feel genuinely worth living.
Will medication fix BPD?
Medication is not a primary treatment for BPD. Current evidence-based guidelines are clear: psychotherapy is the main and most effective treatment. No medication has been shown to reliably treat the core features of BPD — the emotional instability, the identity struggles, the relational patterns. That said, medication can sometimes play a supporting role. If you have a co-occurring condition like severe depression, significant anxiety, or sleep disturbances, targeted medication for those specific symptoms may be helpful alongside therapy. What the research cautions against is relying on medication alone, combining multiple medications without clear targets, or using medications that carry risks of overdose or dependency. The most meaningful and lasting changes in BPD come through learning new skills and developing new ways of understanding yourself and your relationships — and that's the work of therapy.
