Covering old ground from my point of view
As far as I’m concerned, we have paranoia. That’s our disease. Dissassociative Identity is part of how we protect ourselves from the people who gave it to us. It’s a feature, not a bug. Bipolar is part of how we cure ourselves. It’s a winning answer. It’s possible at some point me and Sheer will reintegrate to be a single personality. I’m not sure exactly what that would be like. People treating us for bipolar or DID are quite simply confused about the nature of reality, or are selfish and not concerned with our needs.
