How to cope with borderline personality disorder?

BPD: If in fact you have this difficulty you will need an experienced mental health professional who can see you once or twice weekly for intensive psychotherapy. Best.

EVAL: If you're talking about yourself as possibly having it, get a psychiatric evaluation for borderline PD symptomology and severity, and possible medication management. Then get a referral to a reputable clinician who specializes in borderline PD. Meds and therapy together are the most effective combination. Dialectical Behavior Therapy (DBT) has shown a certain level of effectiveness.
