I have the urge to torture my friends in school
Is it April Fool's? Why do you want to torture your friends?
They make fun of my crappy lifestyle.
It sounds like it may just be a misunderstanding. It's wrong to want to torture your friends. Maybe you all could sit down and talk it out.
I want to wrong them in the worst way possible.
They're your friends, are they not? I don't think it's fair to hurt them just because they disagree with your choices. Have you tried talking to them and discussing why they feel that way?
