Time heals all wounds.
In the meantime, throw yourself wholeheartedly into productive things like your studies, your job, exercise, hobbies, spending time with friends, etc. Do things you couldn't do while you were in a couple. Don't dwell on "what was" - move forward into "what will be".
When you feel you're ready, go to a club or bar, not necessarily to meet someone, but just to be seen. It's quite an ego boost to have guys checking you out
