I was raised a JW, believed it all, became an Elder, tried to teach it with enthusiasm, and was on the fast-track to becoming a CO.
I had a "spiritual" experience, my doctrines unravelled with simple bible reading, and I finally left by DA'ing from the platform after my last Public Talk.
My family and friends shunned me (though not my sister, who had left some time before me - that's her boy in my avatar), and about a couple of years later my marriage broke up (we're divorcing later this year).
I go to church fairly regularly, with no guilt if I miss. I also enjoy a breadth of experience and discussion, trying as many new things as possible, as they appear before me.
IMHO religion isn't a crutch, it's a stepping-stone. Once you've found your objective, I believe it can become a very slippery stepping stone indeed, if it continues to bear all your weight. Nontheless, it remains a useful tool, for those who know how to use it without it using them.
