I'm going to tell my group of friends I don't want to associate with them anymore and cut off contact
Why drop all your friends like that?
Because they think they are better than me.
Are you sure about that? You need to be clear that your friends are toxic or otherwise bad for you before you cut them off like that.
I don't care, I'm not doing this anymore
It's hard to believe that all your friends are toxic. You are seeing it the wrong way or there is something you are not telling me about.
