@MasterLee I have and couldn't find much to support your thesis. Sorry. But given the level of care and compassion you show for the mentally ill I just naturally assumed you'd want to share your research.
@MasterLee Oh no I have studied psychiatry for years at college. I've always taken a passing interest in the subject often read books on psychiatry. Nothing I've read supports your thesis. I would be eternally grateful for your help.
