PTSD has nothing to do with weakness. It has everything to do with how our brains deal with things. As it was explained to me - when trauma becomes overwhelming, our brains "flip a switch". While that flipped switch may help us survive the trauma, it also blocks our emotions from being processed properly, leaving us stuck at the point where the trauma happened. The type and amount of trauma experienced, that causes that switch to flip, is almost irrelevant, in a way. Your situation isn't comparable to what anyone else has gone through. Yours isn't "less than" or "more than" because of the details. What does matter is, are you stuck, because of your experiences, and can treatment for PTSD help you?
