When I was in the hospital, I picked up packets on Schizophrenia and Schizoaffective disorder. The problem is though, is that what could be one symptom of one disorder could also be another symptom of something different. The hallucinations were probably stress induced at first, but when I try and go to sleep now I hear voices inside my head. I do understand they're in my head, but that doesn't make it any less irritating or exhuasting.
