Well this is what I think about these two illnesses. I think schizoaffective disorder is alot worse then schizophremia.Cause it has schizophremia,bipolar and major depression. I think the reason why is cause I have schizoaffective disorder and living with it.Is very hard to live with it. I don't get it cause they both are severely disordered conditions but schizoaffective disorder is worst.
