Help

So I used to heva a best friend but since the other People in out old "friend Group" started to make Fun of him i stopped talking to him. And now i'm here tellyng myself that i'm a piece of sjhit and that i should go and talk to him, but i never do. The thing is that he dosen't talk to anyone and i also do. I always tell myself to go and talk with him but i never end up doing it. I don't know what is holding me back. I feel Like shit, i have no friends so i talk to no one and i sometimes think about suicide. In a few days evey person in 8th grade is gonna go to a party organised by The School and i have no one to go with. I'm so fucking Lost, sad and scared.
