I am in love with my childhood friend.But I didnt express my feelings to her coz of fear.I joined her col which is miles away from my home only for the reason that I might get her!But then I got to know that she is committed with some other guy.I literally cried that day..:(...I still cant forget her..what should I do??

The friend zone sucks!
If you go away, that would be a fresh start for you and as soon as you start getting interested in new girls and making new friends you WILL forget her, I can assure you that. And if you start getting interested in a girl, ask her out right away! don't keep your feelings cuz it only gets worse later. hope this helped
