I had a situation occur which tossed me into PTSD. Everyone who hears the story of the accident can see why. It really messed me up mentally for years and will effect me for the rest of my life I guess. I was depressed before this accident and now looking back the symptoms were to a lesser extent the same as my full blown PTSD. I have been wondering if I had PTSD before the "event" a fews years ago. I had some traumatic experiences but nothing like the accident. I know it is possible but how could one decide if he/she had PTSD essentially from childhood.?
