So we know PTSD is caused by life threatening or physically unsafe situations like war, rape, torture, car accidents, etc... but we also know that two people can be in the same car accident and only one get PTSD. What causes some people to develop PTSD and others not? My husband said something interesting that it wasn't so much about having experienced these life threatening situations but about what it meant to your identity or about you in general. In war the things that haunts soldiers is the things they were made to do, in rape that they were helpless and anyone could overpower and enter their body, or car accidents that cars are unsafe and will kill you etc. What do you think? Why are some people "predisposed" to PTSD and others not?
