I know it may be hard, going through a break up, but do realise that eventually, you it won't be. There must be a reason that he broke up with you (I'm not saying it's your fault). It may have been an issue with him or whatever.
But if it didn't work the first time, it probably won't work again. I know it's difficult now, as it just happened. The best thing you could do for yourself though, is to just keep yourself busy, and try and get over it. Hang out with your friends, meet new people, keep yourself busy. I know you may not want to do that straight away, but you must, as soon as you feel you can.
The worst thing to do would be to keep going over it in your head, trying to figure out how you can get him back. You'll fine plenty of more boy's that you will like, but only if you feel you can move on.
