I know this might be a silly question- but how different is this spectrum from one end to the other. I have a friend who is on the spectrum and he seems to get manic and aggressive to the point of hospitalization every few months. I seem to suffer from depression most of the time, with the odd bout of mania/ hypomania which doesn't last more than a week!! I have been in hospital about 4 times last year, with psychosis, but I'm wondering whether my diagnosis of Bipolar Affective Psychosis is wrong!? How can I be so difference to my friend??????
