I suppose you've already gotten this worked out. but there was one thing you said. you said something like "I've lost my reason for living" or something like that.. dude.. it was a crush.. you never even had anything with her. you can't call that your reason for living. if it is, you need to find a new reason for living.

perhaps I'm not one to talk though, as I said the same thing after my last gf broke up with me. I eventually got over it (sort of) life goes on.. perhaps it won't treat you fairly all the time, but it does go on. and after some time passes, and you're happy again, you'll be thankful you didn't end your life when it was bad, because then it would have never gotten good again.
