This is not helpful probably, but I realize at it's core (at least partially) is not eating numbs the pain (or just hardens you to deal with pain, which I already have, physical and emotional and psychological), and it also seems just a response to unbearable stress. I used to think it was anxiety or depression, but I think when there's no way out, or so it seems, too much stress or not enough reserves to contend with it, then there's anxiety, then there's sort of depression/ worn out (for me), then it just seems matter of fact to stop eating. I know they say you get brain damage in as little as 24 hours, which is all I need, but after 40+ years of one meal/ day most days, definitely work days, I can't tolerate otherwise well, anyway. I've considered eating better would help deal with stress, but no, at least not at this stage of the game. And it just seems the logical response to stop entirely. I really have come to appreciate first hand how hard it is to eat when there is no appetitite, or desire. It's quite repulsive.
