Since I was 15, I have been in a dreamlike state, which I feared to be Depersonalisation disorder. I am 29 now and this feeling has not gone away, even for a moment, in the last 14 years. I have done more searching and found this thing called Oneirophrenia. I am aware that I have sugar problems and need to get it under control, but do not know exactly what to get tested for. Can Oneirophrenia last this long without any relief?Which tests would determine this diagnosis?
