My situation is so similar to yours it's insane. I am on my 3rd stress leave right now. I want to try going back to work but I'm terrified that with my rapid cycling that it's going to push me into psychosis with the lack of sleep. I go through my phases every couple of days but have had several in one day. It's exhausting. I'm on my 2nd day of maybe an hour or two of sleep. I'm worried I'm going to shut down on turkey day.
