Talk to a professional
If you are unhappy with yourself (some people are just more emotionally reactive than others) and truely think that your inclination for drama is excessive, talk to a professional counselor. Your reactive pattern to events could have alot to do with having an ex a as well as many other psycho-social factors. SR is a great place for support, yet success for the individual ultimately happens when they take self-directed proactive action. At times I'm convinced my GF has hystrionic personality disorder (she really just drinks too much occasionally and is goinv through a stressful BK) but, is balanced the rest of the time. A good counselor will help you figure yourself out and effect change if it's what you want.
