Echoing what everyone else is saying, self improvement should be your first priority. If you don't like yourself, why would anyone else? I'd definitely recommend going back to school. Also, I know it's really difficult to forget about someone you cared about, but obsessing over your ex will not make your life any easier; the best way to get over her is probably just to meet other girls (again, going to school will help with this); I'd first focus on just making friends. The quality of one's relationships (including friendships) is the thing most correlated to their happiness.
(I feel kinda hypocritical saying this because my s*** isn't together at all, but the advice is sound).
