I was exposed to JW's as a child. My mother was told the end of the world was arriving in 1975. She was kicked out in 1976 when it didn't come but went back (without me) a few years later. So, while I was not a JW, it was the only religion I knew. When, as a young 20's adult, I had life issues and dealt with substance abuse, I attempted suicide, and felt that God stopped me, I was primed to join a cult.... and my mother sent Jehovah's Witnesses back into my life.
They verified that God did prevent my suicide in the manner I believed and they told me that God has a purpose for me, just as I suspected He did.
In short, I. needed psychological help, but got played by goofballs who seemed normal and used my need for help to take advantage and have me sell their magazines.
