I was so young, and the Lie was all I knew. My family had kept me completely isolated from the outside world. When I saw the hypocrisy, it all happened at once. My natural logic kicked in and said "wait a minute - they are hypocrites and it is all a bunch of lies. There *is* no God." So I left the religion, and my family, in one fell swoop. One Thursday night I said "no KH", and 3 weeks later (thanks Mom, for kicking me out), I had my own apartment and a new job.
Emotional attachments to my 'family' - well, that took a long time, and has left a gap that, due to my social ineptitude, has never been filled. I've never missed "god", though. I am a happy heathen in that sense.
