hey
it`s seems to me, freewill..that you may have a shock...and that it MAY BE a result of the memorie.
but Post traumatic disorder is somehting people have for a long time... it makes their life wors.....

i mean- if you just felt a shock adn then you went on and everyhting became gradually to normal i don`t think you have this dessorder.

do you have this "shock" oftern when you have small accidents? i think that`s what important here.
DISORDERS are a serious thing....
