E-man,
Great topic. I've given a great deal of thought to this, having been "born into" the Troof (fourth generation).
I suspect that the alcoholism and depression that runs in my family may have predisposed my forebears to become JWs. I don't think that the Troof made them crazy; I think it made them crazier.
That said, I really believe that the constant repression, denial of normal feelings as "untheocratic," unrealistic expectations, and rigid rule-enforcing led to a whole boatload of psychic damage (I use the term "psychic" to mean a combination of mental, emotional and spiritual--has nothing to do with Miss Cleo!).
I left at 18--as soon as I legally could get out from under my parents' thumb--and have spent the last two decades attempting to "undo" the damage. I get very frustrated with people who think I should just "get over it." After all, they've got supportive families, don't they? Families that might even talk to them without telling them they deserve to die for rejecting Jehovah.
Yeah, there's damage, including an on-going sense of unworthiness (no matter how much I succeed, it's never enough, because it's not Theocratic success). I keep plugging away, though.
