Howdy and Welcome!
It's been a year and a month since I left. I went through stages of belief - disagreements with the Org which lead to my leaving, finding another group that would accommodate my beliefs and seemed to have new ones in harmony with my thinking, eventually disagreeing and searching/thinking some more.
I plugged away at it hard, forcing myself to put into words what I believed and not stop challenging it until I was at a place of peace. It took being quiet long enough each day to learn to hear that little voice inside that was whispering, "But I don't like that/can't agree with that/feel there's some dishonesty here," etc.
It takes time, focus, and the most painful honesty. It takes the work of building a new community and - literally - blazing new trails in our brains.
It also takes learning to live with uncertainty - not begrudgingly, but peacefully. As JWs, we were used to having all the answers handed to us or a convenient shelf to put them on until it was the "right" time for "Jehovah" to publish a Watchtower with the answer in it. All we had to do was pop in a CD and BANG! there's every answer you could ever want to any question you could think of and quite a few that really weren't anyone else's business anyway.
Figuring out what you believe means spending a lot of time saying, "I don't know." It means learning how to live in the tension between what you want to know and understand and the not-knowing, not-understanding, not-having-a-place-to-find-all-the-answers.
I'm at a place now where - emotionally, spiritually - I can rest. I have found friends who are on the same quest and who support my search, even if what I find disagrees with their own discoveries.
It's hard. It's frightening. There will be times when you want to go back to the dysfunction just for the comfort of the illusion of knowing - times when you want to throw out your reason and intelligence and just decide to believe again for the sweet relief of imagined security. And, our imaginations being what they are, what we imagine can feel so real - especially if we want it badly enough.
The best answer for me was honesty, good friends, and time.
