What I had was classic short-term PTSD. From an evolutionary perspective, it’s exactly the response you want to have when your life is in danger: you want to be vigilant, you want to avoid situations where you are not in control, you want to react to strange noises, you want to sleep lightly and wake easily, you want to have flashbacks and nightmares that remind you of specific threats to your life, and you want to be, by turns, angry and depressed.
