I have been a non-christian for 5 years, a non-theist for approximately 2 years, and have not believed in Hell for at least 7 years. Still, though, I have residual fears of eternal punishment left over from my stint in the Southern Fundie Baptist world back in high school. I still have these nagging thoughts of "well, WHAT IF I am wrong and they are right?" even though logically I think it is highly unlikely that any sort of afterlife exists at all.
How do the rest of you handle these sorts of thoughts, other than by telling yourself that it's all just make-believe? I have so much fear and guilt associated with leaving my family's faith, but at the same time, I think they're all a little daft for being fully grown adults and believing in what are obviously fairy tales. How do you deal with feeling guilty and afraid over not believing?
