Celebrities with diagnosed mental illnesses?

Celebrities with mental illnesses like bipolar disorder, OCD, autism, schizoid disorder, and others but it has to be serious. Not like someone saying "oh, im ocd about keeping my house clean" but it is a real problem. I know Howie Mandel has OCD. and was Sylvia Plath bipolar? thank you!
Update: P.S. they dont have to be celebrities they can be fictional characters too.
