I had a pychotic episode, a pychosis, which happened to me when I was 18... Too much drugs, some sex, rock and roll, all that... Plus no sleep, you really got to sleep. Anyway, I fell ill, was in hospital on a ward for like a month, under lock and key... Then when I got out as an out patient on olanzapine, I asked to stop it so I got myself weened off that, I hated the side effects... I was diagnosed as having Bipolar Disorder.
My mother, in the 1960's, was hospitalised and diagnosed as having Manic Depression... I figure, it's the same thing, only what they called it back then.
