Something is wrong with me?

You poor thing! Well you should probably start out by getting a therapist or shrink. If you don't have the money or something than you at least see a doctor or gets some pills for your depression. If none of this will do find someone ANYONE to talk to, it can be a parent, doctor, friend, or even write in a journal it's helped me out. Just take care of yourself and don't let her overtake you. You are stronger it's you body and she can't change that!
