I recently ended a relationship with a woman I now suspect has borderline personality disorder. From the very beginning, she was given to very quick mood swings and to either worshipping me or being angry with me. After I talked to her about how disproportionate and damaging her anger was, she evolved into a pattern of just shutting down emotionally on me, sometimes for days or weeks. She also saw all issues, in the world in addition to in our personal lives, as black or white (another symptom, I've learned). However, she's not suicidal, not self-mutilating, did not try to stop me from breaking up with her and puts on this front of being very together, in fact of being arrogant. Could she have borderline personality disorder, or do you think it's more likely that she's just insecure and carrying a lot of baggage. For those that have her symptoms (mood changes, inappropriate anger, pouting for weeks, not seeing things for what they really are), is Prozac effective?
