I get psychosis during mania and mixed episodes. It makes things VERY confusing to say the least. I understand where you are coming from.

One thing is that I've become more clear-headed taking antipsychotic meds and while I still get psychotic sometimes, I usually recognize symptoms and can call my pdoc to handle it. For me it comes on gradually. So maybe time will help you.

For awhile a therapist thought I had schizoaffective disorder which is where you have psychosis and mood episodes but not at the same time. For me, it was ultimately determined I had bipolar 1 with psychosis. I can see why you are confused being given different diagnoses or just the bipolar diagnosis to get treatment going. Very confusing. Only a psychiatrist can determine what's happening and I think your DID needs treatment, too. I've heard therapy helps. I hope you can get help. Keep us posted.
