The dissociating can be a symptom of overwhelm, which is why I was cautioning around it.
It definitely can be comfortable, after all, it's a safety measure.
I'm currently comfortably ensconced in my little dissociative, depressed, dark hole. It's very comforting. This darkness is safety, as opposed to the darkness I'm trying to run from... kinda a bit physically uncomfortable because of the pressure in my chest, and the constant urge to cry (headaches), but whatever. It's safe from the scarier stuff.
