Borderline Personality Disorder

Hi. I have had mental issues for a long time now. I have seen many counselors, have been on medication for depression and anxiety. I was molested when I was younger, was physically and emotionally abused by past partners. I have even been admitted to the mental ward at the hospital. I don't feel that anything is working. I go through weird bouts of being angry, and saying things or doing things that emotionally hurt other people. I feel depressed most of the time. I always feel that I am nothing but worthless, and I will never make anything of myself. I researched the internet for what could possibly be wrong with me, and I came across borderline personality disorder. Strangly enough, all the symptoms seem to match what I am feeling, or my actions, with the exception that I would not try to commit suicide. My question is.....does this sound like something I may possibly have. What should I do about it. Do you think it is something else entirely? Please help!
