I'd be interested in finding out if there are any statistics related to leaving Scientology and symptoms of post-traumatic stress disorder or generalized anxiety. There may be.

Yeah, you find that, let us know.

Found some things, basically related to brainwashing. http://www.xenu.net/archive/personal_story/funkydonny.html

More where that came from, but look around.

I suppose members of Scientology may be more likely than not to be depressed or mentally ill since that is who they try to recruit. Making it hard to tell if ex members were already paranoid before joining.

I'm thinking that's very likely, boner.
