If they spent hours asking you questions, then that does sound like the kind of psych screening I was imagining. Besides questions, did they give you any tests?

Medially, I would hope you could get a doctor to do a complete blood count (CBC) and have a neurologist screen you as well. In my experience, doctors can get tunnel vision once a psychiatric diagnosis is on the table.

But it's great you were able to talk to the psych folks.
