I grew up Lutheran, went to Sunday school every week, got confirmed and all that good stuff. Even back then I think I was leaning towards agnosticism and there I remained stuck for over a decade. Letting go of the belief that there must be some sort of God strangely wasn't that hard, but leaving it behind completely is terribly difficult.
Thinking there is a God is such a wonderful crutch. In the last year since I've decided that I, indeed, am an atheist I've prayed and asked God to get me out of trouble more than once. In a pinch, I'll say something like "please God don't let this stinky homeless person sit down next to me" when I'm on the El. Once my temporary problem is solved (without any smiting) I brush it off and scold myself for being inconsistent. Believing in God would be so much easier.
