DannyBoy, you're still young. I was so much older than you before I found out. You still have lots of time to rediscover the world. Don't look back! This is going to be so much fun for you -- like falling in love again. And it's not too late for your kids either; they haven't been as brainwashed. And your wife is with you on this. You are in an enviable spot. Enjoy it here; get your anger out, but don't linger long; there's so much to do now that you have all this extra time and money that the church no longer has claim to.
Yeah, I was just on the far side of 40 when it all finally crystallized for me and I said enough. It had been a long time coming, and if I'd had the courage or the emotional energy, or the sense that there was support, I'd have left a good 12-15 years earlier than I did. Thank Spider Pig for the internet. Just think - you've got the rest of your 20s and all your 30s, 40s and beyond. I get being pissed over what you lost, but you'll be able to salvage SOO much more life time than some of us. Mrs. D speaks truth. Do what you have to to metabolize your (highly justified) anger and spend some time finding out who your are and who you choose to be (you get to CHOOSE!) without the church distorting that. But don't let the church steal any more of your life.
I'm not trying to minimize what you've lost and you should go through all the stages of processing that loss just as you need to. But again, you are in an enviable position in lots of ways. Revel in that!
