I dont have these problems that you listed but I know someone who has - my significant other. We had all been under the assumption that she had DID but no testing has ever been done. She was diagnosed schizoaffective for the reasons being exactly what you have posted. its hard to explain but Ill try. She created imaginary friends to play with and be with in social situations. I guess when she was a kid, one of her relatives made fun of her for having imaginary friends so she let them believe her imaginary friends were gone, and she pretended her imaginary friends could go invisable and walk through walls to hide from the relatives and go invisible and go inside her and share her eyes to see with. as this fairy tale continued she forgot her imaginary friends were just pretend playmates. So over time she really believed she had these alters inside her that she was co conscious with. it was at the family reunion a couple weeks ago that she was reminded by a relative that she had imaginary friends when she was little. She went to her therapist and asked for diagnostic testing to varify whether she had DID or not. after the testing and finding out she had schizoaffective insteaf of DID the psychiatrist explained to her the differences of her alters and DID alters. they are very simular but yet different at the same time. one of the main difference is that with medication her alters would disappear. and they have.
