Sometimes it feels that way. The panic,fear and anxiety is so intense and all the lashing out and impulsiveness is out of self-preservation. Just a thought.

EDIT: Yeah I see what you all are saying but.. Rejection, abandonement, criticism... these are part of having relationships and friendships, etc. They are just components to dealing with human beings; a very flakey, conflicted species. maybe we are not afraid of all the nice things about having relationships/friendships but the things that make us freakout.. are things that come with the package.. 

I suspect personally that I have been conditioned to expect way more of the bad stuff from people because I had a very abusive and isolated childhood. I literally learnt to associate pain with human relationships. Therefore I have been conditioned to fear human relationships. Also, I find that my reactions are much more severe, the closer I am to someone.. so perhaps it should be refined more to a fear of intimacy, because real intimacy involves things like criticism for sure.
