Based on the title, I would assume that the song is about manic depression. It also describes textbook borderline personality disorder: "She loves you and hates you; you break down, she feels good. She will bleed from insecurity." A borderline preys (not always intentionally) on a person who has good intentions and wants to help them. They are usually very dependent on others, and they get their power from making other people "need" them.
