I have chronic migraine ontop of it and emotions, from how strong they are seem to be a massive trigger. Even when I'm not crying myself sick and straight into a 3 day nightmare and it's boiling rage that stays in my head, I'm shaking and feeling nausea real bad. Even before a migraine kicks in, or without it kicking in at all my emotions legitimately make my feel physically ill. I have to emotionally shut down and feel nothing at all to stop feeling so sick ontop of whatever negative emotion I was feeling. Guess that coping mech is still worth something at least.
