A common misperception about ptsd is that it results from discrete traumatic events or episodes. It doesn't in general. More often it results from discrete or continuous traumatic events or episodes together with one or more of alienation, lack of social support, or ostracization. That is one reason why not everyone who experiences a shared traumatic event will develop PTSD.
So what is maladaptive are there breakdown in social ties and cultural/social infrastructure and process for supporting humans going though hell, not, in fact, my PTSD, thanks
