I have SchizoAffective Disorder, I also have a Major Mood disorder, and depression. When I was 5, they thought I had autism, but I did an IQ test and had the mental age of 12, and said autism didn't apply to me because I have a high IQ. They didn't know about high-functioning autism back then. So I think I was misdiagnosed. I think I am on the spectrum somewhere on the high end. I learn fast, but sometimes forget what I learned. I am 57 now.
