I'm so sorry about your friend!!! I've had some just like that!!! Briester is right!!! They are not much of a friend if they are only around for good stuff or drop ya when the tough gets tougher!!!! Please don't give up though!!! Is there any one else you can talk to!!
I really hope there is someone you can talk to because even though you have poeple here its not the same as having someone in real life to talk to!!!!

Hugs to u!!!
