i totally understand!!!i have PTSD from hitting my head on the pavement during a pedistrian accident and from 3 other accidents too where i smashed my head on sewer covers during the accidents.extreme anger is what i felt and still feel. i do try to control myself rarely screaming or shouting, but hold it inside. i can't concentrate for more than a few minutes, and i still can hear in my head the sound of it smashing it on the ground. oh yes i forgot i was assulted by an exfiance too and he bashed my head in the pavement too.if someone here could put the trigger symbol on here for me i would appreciate it. i don't know how to do it.again the anger is the main issue with me too. i see a doc and t and they've helped greatly.
