How about the federal government? I could see the VA needing registered dietitian. But almost any job would be a good thing. I actually saw a article this morning about the FAA looking to hire those with mental health issues. I work for the federal government and, by and large, if you get though the probation period you have a job for life and very good benefits. You could start at an entry level job to get in the door.

BTW I lived at home until I was 32 (with some years away for school) noting wrong with that.
