I used to communicate with this guy who was interested in schizophrenia and wrote a book about it. I got to be pretty good friends with him and communicate with him for about ten years. He passed away about five years ago. Communicating with him and reading some of the stuff he compiled really helped me understand what led to my psychotic breaks when I was younger.
I was interested in C G Jung theories because they mainly came out of the work he did with schizophrenics plus his own period which some believe was like a long type of psychosis. I still like watching YouTube videos that discuss his psychology.
