Yep, I've been there, and it wasn't any fun to me. I was under extreme stress during those periods of time when I dissociated though. I found myself dissociating for several days continuously. Then, I got better & it now comes for shorter periods of time. Like, one day, or a few hours...that kind of thing.
The loss of appetite has always been a stress and/or major depression symbol, and comes more quickly (as well as much more often) than the dissociation for me.
Gentle hugs to you ~ this *will* pass!
