a couple weeks ago i broke up with my gf of almost 2 years. we were doing the long distance relationship for about 6mo. apparently she couldnt handle it anymore. a couple of days ago i call her to see what she has been up to, to see if we can still be friends. this girl meant the world to me and i would do anything for her. this call turned a complete 180 for me when i found out that she found a new man, is sleeping with him, and even wants to marry him (this detail i found when i was deleting her off my facebook.com and came across her new xanga). wtf... i went to visit her the week we broke up and i could tell we definately still had strong feelings for each other. she even mentioned that she wasn't over me when i emailed her a week after we broke up. she had just broken up with me and now she has a new bf that she is apparantly madly in love with. btw, i'm 21 and she is 20. we are really open with each other and i know she was not seeing this guy behind my back. she said it came very fast and the emotions were strong with this guy. this situation coupled with one of my close buddy letting me down and continually abusing my generosity and stress from finals coming up, i really really dont know how to handle this situation. i can barely sleep and i'm a zombie in class. what can i do to alleviate some of this depression?
