for my case, the best way was to be with friends, i mean close ones. go out with them, do watever u want. u'll forget the sad moments for a moment.think positively that u deserve someone else better....juz be patient and God has better plans for u...at least it works for me, i got over mine in few months time, though the first 2 months was alot of hell since i have to face my ex everyday (same class though)...
