I was friendly with someone in highschool who came down with it too, but he got treatment early & seems to have kept his life together.
Are you aware of that study in Papua/Malaysia/Indonesia (can't recall which) describing mass onset of schizophrenic symptoms when village people relocated to strict factory routines? Sadly don't recall the exact paper but suggested stress induced group psychosis was quite common when primitive peoples are suddenly shifted to a modern lifestyle, even described onset as a crude coping mechanism.
