Hey, man... Kinda got some experience about this over here. Best thing you can do right now is to go out with your friends. Hell, go out every single night, even if it's only to take a walk. In about a week you should be feeling better.
Also, I know this is a bit unorthodox, but revenge sex is pretty good too. If you fuck everything that moves for a while, you should be over her in no time.
