emotional abuse, especially from a friend, can be very devastating and that could be the only thing that caused your response. have you done this often? or recently? i know that it upsets me greatly to have a friend go off on me. it hasn't happened but once lately and i was ruined for weeks. i felt as if i had been punched in the gut and cried and cried. so, it can be just the response to the hurt you felt. if you can talk to a therapist, try that. keep me updated and PM me if you need to. xoxoxo pat
