When I was psychotic my anxiety was off the scale. I narrowly escaped my enemies many times. People were reading my mind all the time. If we ever did achieve the ability for telepathy people will hate it because it is a tremendous invasion of privacy. Life for someone in psychosis is often very much like Chinese water torture.
Every day is another drop.
And it is very real. They sometimes can't even tell you what is going on. The lucky ones don't remember much of their psychosis. I don't know that anyone is doing any research to see if psychosis causes Post Traumatic Stress Disorder, or changes people forever like the holocaust or Great Depression. I think it does.
