Quick answer: Borderline personality disorder (BPD) involves intense, shifting emotions, fear of abandonment, unstable relationships and self-image, impulsive behavior and, often, self-harm. It’s treatable, and dialectical behavior therapy (DBT) has the strongest evidence. Residential treatment can help when self-harm, crises or co-occurring conditions make outpatient care unsafe or ineffective.
How we put this guide together
Amend Treatment is a licensed residential mental health program in Malibu, California, with a six-bed maximum, that treats borderline personality disorder. This guide draws on data from the National Institute of Mental Health (NIMH). It’s meant to inform, not diagnose.
How common is BPD?
According to NIMH, the past-year prevalence of borderline personality disorder among U.S. adults was 1.4%, and 84.5% of people with BPD also had at least one other mental disorder, most often anxiety, mood or substance use disorders.

Real or imagined rejection can trigger overwhelming panic, leading to frantic efforts to avoid being left.
2. Stormy relationships
Relationships may swing between closeness and conflict, with others seen as all good or all bad.
3. An unstable sense of self
Goals, values and identity may shift quickly, leaving people unsure of who they are.
4. Impulsive, risky behavior
Impulsive spending, substance use, unsafe sex or reckless driving are common, often as ways to cope with emotional pain.
5. Self-harm and suicidal behavior
Self-injury and suicidal thoughts or behavior are common in BPD and require serious, compassionate attention.
6. Rapid emotional shifts
Moods can change quickly and intensely, often in response to interpersonal stress.
7. Chronic emptiness and intense anger
Many people with BPD describe a persistent emptiness and struggle with anger that feels hard to control.
8. DBT has the strongest evidence
Dialectical behavior therapy was developed for BPD and teaches skills in mindfulness, distress tolerance, emotion regulation and interpersonal effectiveness. Comprehensive DBT includes individual therapy, skills training and coaching.
9. When residential treatment helps
Residential care may help when self-harm or crises are frequent, outpatient care hasn’t worked, or co-occurring depression, trauma or substance use complicate treatment. Amend provides BPD treatment using DBT, trauma-focused therapy and family work in a six-bed setting. Call (833) 912-6363.
