Look, it is you who have the idea that a psychiatrists knows anything about this disorder. I would say there is a 95% chance he dont. This is highly under and misdiagnosed. There is no exoteric knowlege that says "only for psychiatrists and doctors". Everything is open in medical databases with publications in medical journals. There is no publication at all saying that anti-psychotics have any benefits in depersonalization in its primary form. There is publication saying it is often misunderstood by psychiatrists as symptoms of a psychotic state and a treatment for such is started up. I don't know if you have depersonalization in its primary form. I have seen many of this forum who have these symptoms secondary to another condition. Some with secondary depersonalization to another state might have benefits of anti-psychotics.
Sadly, I don't go to psychiatrists hoping for them to understand Dp/Dr or me anymore. I have gone to many and none of them truly helped me. But I know what I want out of the visit. I know that I need a medication that assists me in my healing process. I do work on myself, and I have seen changes. But sometimes, I would like things to be clearer, to be less tiring. I do have OCD. Many types of it, since I was a child. I do think it is one of the causes of dp coming into my life.
Did u mean by "dp in its primary form" as dp without any other influence from another mental illness ?
If so, then I do agree with you. I think that solving my "ocd problems" and healing from them is to trigger the dpdr healing also.
