OK so things are startign to get better for me
But there's only one thing that I'm not sure what to do about
So there's this guy that liked me and we were pretty good friends but then he became obsessed with me and always bought me stuff and I told him a thousand time that I didn't like him like that and so did mass of my friends but he didn't listen and still thought that I did and then I meant this kid that I really do like a lot and my friend tried to start with him telling him he was going to get jumped and he better watch his back and stuff and kept making threats to him and then he started yelling at me and calling me a and and I'm not sure really what to do about him like he is obsessed with me and I don't know I guess just the way that he acted scared me like what if he does something or really tries to hurt me or my boy what should I do about it all

Let me see your friend threatened to have him beat up and you wonder why he goes off.

Leave him alone, don't talk with him, and go your separate ways

If you two are in the same school, get the counsellor involved...
Talk about such things, you should be careful with people who have an obsession, especially if you are the object of his obsession,
We never know when a line will be crossed and most of those obsessed are not rationally thinking when their object of obsession is involved.

Tell your parents, so they know when you go out,and protect you if needed.
