it would be remarkable that he could be suffering from these things and still get a job. I have a family member who suffers from this and she can't get hired anywhere. She has a hard time finding a place to live. Everywhere she goes she ends up thinking there are voices in the wall coming through the electrical wiring or whatever. Sometimes she is very convincing and it seems as if it could be true. But it is not real. But I want to emphasize that she can seem totally normal and not crazy. She is lucid, except for the hallucinations. It is impossible to function day to day and experience these things. He must have been living hell.
