Sometimes I Act Crazy: Living with Borderline Personality Disorder by Jerold J. Kreisman and Hal Straus.
Various forms of treatment are helpful for BLPD, but the one which has been found most successful and which has the best research base is DBT (Dialectical Behavior Therapy). Certified DBT includes both individual and group work, and engagement with several therapists who work together as a team. There are a number of providers and programs which include some DBT as part of their services in San Diego, but I know of only two fully trained and certified DBT teams:
The DBT Center off I-15 and Pomerado Road
Sue Rose, LCSW is the contact for the Mission Valley DBT Team.
