Hmmm. Like I said, I just read about DID a couple of weeks ago.
I've been trying to match my experience of psychosis with the standard categories for several years, and the closest match I found was "brief reactive psychosis" (aka "hysteric psychosis"). Apparently "hysteric psychosis" involves dissociation. When I get depressed, I sometimes feel disconnected from my body. There is supposed to be a traumatic event though, and I can't think what that would have been in my psychosis. IDK
Oh well, I guess DID is probably not relevant to my problems. Thanks for the responses
