hello,
I'm sorry that things turned out that way. Losing a person you care for and having them break your trust is never easy. trying to get over a person i think is one of the hardest things to do. Its something that takes time. although it hurts quite a bit now, after awhile you'll slowly get over him. though you should never give up on and harm yourself. i can promise you that he isn't worth it. no guy or girl or person is worth committing suicide. you seem like a nice person and you deserve way better than someone like him. i'm sorry that your friends seem to be making you feel worse about everything but they mean well. they just care about you and don't want to see you sad.
i don't know if any of this helps, but you really do seem like a good person, and one day you will find happiness. don't give up on that ever! because it will happen.
I'm new to all of this and this site, so if there's anything i could do to help or if you need someone to talk to I'd be happy to listen.
i know you'll be able to get over this guy, because i can tell that he doesn't deserve you and i hope you'll feel better soon.
