Well, I wasn't there and I don't know the personalities of those girls...

what I do know is that anyone who has been traumatized, whether they have PTSD resulting from it or not, will be sensitized to similar situations.

If you do suffer from PTSD, then nearly anything that has any element of your trauma, will retraumatize you. (This is in general, without therapy etc.)

If you are identifying with other's trauma, that is common. IMO you need to continue to seek answers in your own life to be sure you are not also being triggered to parts of a trauma situation you did experience.

TC You aren't a terrible person unless you are leading us all on, which I am not worried about
