Rather, I believe that the psychosis may well be a manifestation of an underlying and undiagnosed mental illness, which can include schizophrenia, but there are infinite other possibilities. I also assume that this would be diagnosed, if the person dealing with psychosis is already receiving treatment.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
