Hate being around people

And I hate trying new things. I will self-sabotage forever it seems, but I want this to change. I WANT to be able to go out places without constantly being bothered by others. I've always been told to just ignore, tune them out, etc but I never have been able to. Something little always sets me off and I have to get away from that environment asap.

The past always presents itself to me and I can never let things go, either.

You say you have always been told to tune them out and ignore the ones who bother you. who are these well wishers/friends who have told you? would it not be easy to hang out with these people rather than the ones who bother you?
