Thinker, I SOOOoOoOoOooo identify with almost everything you said in your intro post. It still amazes me how coming here is like looking in a mirror. That's the power of the cult, I suppose, that we could have such similar experiences.
Definitely try other churches. Research first. Most of them have online presences where you can check them out first. Make sure it's going to have the right vibe for you. If, unlike me, you start leaning toward atheism, you can make peace with that too, as many others have here.
That is a HUGE STEP that first time you don't tell the new teachers you are witnesses! I remember those days! I did say that the teachers might get mixed messages, and explain you are in the process of leaving, and letting the kids decide what they feel comfortable with.
OMG, welcome and im so glad you're here.
