I don't have a life anymore?

[Ace]

Well, i was mad at my best friend's friend and than my best friend got al mad at me. He has been mad at me many times but the strange thing is: He only does it on social media like twitter, facebook and such. But all of the times he did i thought to myself. Let it go, Everyone can be mad sometime. But now he goes to far, thanks to him i don't have even one friend left. And the worst thing is: He even made the girl i like hate me. Now thanks to him my parents think i need psychological help because i don't have emotions anymore. But i don't know what i must do, my life is ruined and i've already done 5 suicidal attempts, to no avail. But now i have the idea in my head: I won't die if he's still alive. Can anyone help me get over this and just be normal again?
