Hi, musicandsoul, and welcome to Psych Central! It sounds to me like you' might some version of post-traumatic stress. Here's the link to our forum for that:http://forums.psychcentral.com/post-traumatic-stress/.

I encourage you to find a professional counselor to help you to work through these understandable issues. You are probably suffering more than your friends because you were actually physically hurt during the encounter. My guess, anyway.
