What do you think about me cutting all contacts with my closest friends?
Why do you want to cut off ties with your closest friends?
They told me they hated me and I got pissed at them.
It sounds like you may have gotten into a silly argument. If you lose contact with your friends, it's always a good idea to check in with them from time to time. It could have possibly have been a misunderstanding.
I'm going to ignore them from now on if they don't want me around.
Before you walk away from your friends permanently, you have to find out what is going through their heads that they would say that they hate you. It is likely that you are projecting on to them your own self-doubt and you need to clarify the situation by speaking with them.
