Yes, derealization, to soften the truth of what our reality actually is. My experience with these feelings goes back to early childhood. Then later it seems my brain chose that method for other realities to protect me. Presently it's not enough. Too many bad things. Depression & anxiety are stronger, & dissociation episodes have no memory to tell me what went on during those periods of time The voices use physical harm, & they won't let me sleep enough to allow me to regain my strengths.
