Erica Crompton has written a moving piece for the New York Times describing her struggle to work as a schizophrenic -- actually now her diagnosis is schizoaffective disorder but that doesn't affect the story.
In reading this piece, you may want to say "See, that shows you can work even if you're a schizophrenic." However, her work history has been extremely fragmented. Fragmentation is an inevitable part of schizophrenia, affecting both work and private life. It's part of the disease. By the end of the story, Crompton isn't earning enough to support herself. Maybe most important, Crompton is a talented writer. She has had opportunities that are not open to the vast majority of schizophrenics and she still can't support herself.
I've said it many times. Social Security ought to just go ahead and approve every last disability claim filed by a person suffering from schizophrenia or schizoaffective disorder. Very few people who suffer from either of these conditions are able to maintain regular employment for extended periods of time. Social Security approves a lot of these claims but not all.
