I am an Indian with a history of psychosis living in the United Arab Emirates. During one of my psychoses, I was turned away by 2 mental hospitals in this country. I dont think 2 hospitals in the country would have lack of space. Hospitals turning away patients seems ridiculous to me. Is this due to discrimination against expatriates or simply because there was nothing they could do once I was in active psychosis?
To answer this properly, you should consult with a medical professional. Your diagnosing doctor should be able to tell you whether a hospital can do anything for you when you are in psychosis. They should also be able to advise you on the specific steps you should take when you are actively having an attack.
As for discrimination, while it may be the case, as long as you are choosing to live there you are going to have to find a way around it. Perhaps others in the expat or Indian communities can tell you where they have had successful services rendered.
