My husband, (Baalam's Ass) was a Bethelite in 77-78 ish. After hearing his accounts of life and experiences there I believe that many, after seeing how the organization is actually run, are severely stumbled.
Those without a decent support system, are broke, and disillusioned, can easily become despondent. Who can they trust to share their doubts with? Certainly not their family, if they are Staunch JWs!
I had a close JW friend whose boyfriend went to Beth-Hell, came home and shot himself. He was a handsome, intelligent, person who couldn't bear the burden of "The Truth" anymore.
