When I was 16, my mother and I finally escaped from my abusive father, who had been an elder for years. She sought help from the elders for years. The only help they provided was telling her what a good little JW wifey she was for keeping secret and not "bringing reproach upon Jehovah's name", and to pray more. It took her 29 years to get away from him.
When we got away from him, we started over in a new town. Initially, we had nothing, except a suitcase of clothes. No job, no car, no place to live. Eventually, things started to fall in place (without the assistance of our "brothers and sisters") and we were able to go back and get only some of our stuff that we had left behind.
After it was all said and done, I told my mother that I didn't want to be a Witness anymore. I just couldn't imagine living forever with these people who wouldn't help us. Her response was "I know. I feel that way too sometimes, but there's nothing else out there." I attempted suicide shortly afterwards. It took another seven for me to be able to stop going to meetings and attempt a fade, but this is what precipitated my decision to leave. I would rather be dead than with the Witnesses, so how bad could the world be?
The final straw where I said I absolutely will not step foot in a Kingdom Hall again? It was a drama at the summer convention. My mom convinced me to go on that one day because she knew when I was growing up, the dramas were always my favorite part of an otherwise boring 4 days. (Showing my age).
The drama was about Moses and Korah, and how Korah would not listen to Moses when he came down from the mountain serving as God's mouthpiece. Korah wouldn't accept Moses's authority so the earth opened up and swallowed him. They very clearly lined out the correlation to today. Moses represented the organization/ F&DS. Korah represented any JW that questioned their authority.
I was in my early 20s, and was incensed at the very blatant fear tactics they were using. It was the last JW ANYTHING I went to. That is not why I left, but it was the straw that broke the camel's back, so to speak. It made me realize I was old enough and strong enough to walk away, and the only thing keeping me in the Borg was my own two feet.
