Funny you say that moxie because I always read about how CH makes it so you cannot sit still but I like to press my head into the bed or floor and sit very still in the dark and I also used the term hide from the pain by trying to get into portions of my head that kinda hide from it.
Yeah, the self inflicted pain stuff, hitting, stabbing etc. is pretty normal IMO. We gotta do what we gotta do!
