I have borderline personality disorder and don't know how to deal with it. can it be cured?

Yes, but...: Treatment of any personality disorder requires years and years of treatment with a therapist who is experienced at treating personality disorders. The process is not easy for the patient or the therapist, so few therapists are willing and competent to do so. However, it can be done and is worthwhile despite the pain.

Borderline: It can be stabilized & brought to remission with long-term counseling with a therapist experienced in working with dialectical behavior therapy.
