The scariest part of psychosis is never being sure if it will come back, get better, or get worse. My only suggestion is to knock yourself out with some sleep aids as soon as you get some sign of the psychosis. Did you get any weird warning signs before the heavy breathing? My head usually tends to "pulsate" as I describe it & I usually get a headache & some anxiety, coupled with weird visual disturbances. It's like a migraine with aura, which I also get sometimes, too. If there was a homeopathic cure for psychosis, I'd have found it ages ago. But... I don't mean to be discouraging. I wish you the best until you get back to your homestate to get treated. I know how scary it can be. Take care of yourself.
