It's good that you aren't leaving. Here are some points.
1) Don't change your mind again.
2) Don't say everyone hates you, It makes them hate you even more.
3) Don't fake your Death.
4) If you do don't blame it on your Dad/Mom/Sister/Brother/Grandma or Dog.
5) Make some friends.
6) Don't do drugs or have under age sex. (It's bad for you
)
7) Don't Masturbate (You'll get hairy hands
)
8) Never come back! (Jk)
