All Pied Everything
I wanted to regain my own confidence and my own self-esteem before I was willing to try meeting someone else.
Now there's a good piece of solid advice. Take this time to really get to know yourself. Understand that your likes are just as valid as anyone else's. The last break up I went through was a big bad one, one that left me crying by myself all the time and feeling hopeless and alone. I realized though that my sadness wasn't even really about the person I'd been with. It was about me and my own insecurity.
Don't push things, just be yourself, and surround yourself with comfortable friends. Once you know and love yourself you may be ready to find another person to share your joy with, or you may not. By being true to yourself though if you do find yourself a special someone hopefully it will be someone you don't have to hide your true nature from. Someone you can go out and do all the things you "couldn't do before" with.
Last thing, I agree whole heartedly that contact with your ex must stop immediately. It halts the healing process and prolongs insecurities and false hopes. I know I didn't fully get over my last ex until I said "enough was enough" and stopped talking to him all together. Two years later I still don't really like to see him...
I hope your world becomes stable again soon!
