Hello OP, I found/find myself in a pretty similar situation.

I just started my "coming out" process roughly eight months ago. I live in a conservative Christian town and my parents fit the bill quite well ie. my Dad was a pastor for ten years and my mother was raid by a pastor. I, like you, realized that I had some reservations about Christianity. At a certain point, I stopped forcing myself to try to live like a "good Christian," and found it was very liberating. Two years later, I consider myself agnostic, with the belief that something greater than myself, exists.

Now, as for coming out: it was a slow process. I realized I had issues with Christianity about two years ago. Then, about a year ago I stopped telling myself I was a Christian. I felt fake telling people I was a Christian so around eight months ago I told my Christian brother, who I'm very close with, that I was not a Christian, and he was very accepting. I told my other brother, who I am also close with, and he was also very accepting. With these positive experiences in my mind, I've since opened up to people (Christians) around my community that I'm not a Christian, when they ask questions like, "what church do you go to?" or "how has God been working in your life?" The reception has been mixed. Some friends have been fairly accepting, but I still get the sense they go home and worry about me or pray for me because I've lost my faith. Others have insisted that I will return to Christ and that he just hasn't shown himself to me yet, and I tell them "perhaps so, or perhaps not," which, in some cases, they are unwilling to accept.

I haven't told too many people in total; most likely less than ten. Then again, where I live it's almost assumed I'm a Christian so unless they ask specifically about my faith, this stuff doesn't come up. I guess, if my story can be of any use, I'd tell you that most people are fairly accepting and won't really care all that much, but others will try to cram Christianity down your throat even harder, thinking somehow that you need more dogma than ever. I suspect that to a Christian, leaving one's faith is the saddest thing in the world, and when they see someone do it, they fear.

I feel better about myself now that I'm not actively lying about it. The conversations, as I've mentioned have been mixed, but at least people know where I stand, even if sometimes this means that they do some silly things to try to "reconvert" me. Overall, I'm glad I've come out about; not only do I feel more true to myself, but the fact that it's an intimate piece of knowledge about me has meant that sharing this experience with others has been a bonding point. Furthermore, by gauging others' reactions to my beliefs, I can tell who really cares about me: my emotional health, habits, happiness, joy for life etc, and those who only care for me as or because I'm a Christian.

Sorry for writing a dissertation, I guess I had a lot more to share than I thought I did.
