I don't know if this is the type of answer you are looking for, but the biggest problem for me has been conflict with believing loved ones, especially my wife. She truly believes that I am going to hell, and that is a source of pain for her. We've reached the point where we don't talk about it much, so I'm not sure how often she thinks about it, but just about every Sunday in church the pastor brings up the "fact" that non-believers are destined for eternal punishment.
It has occurred to me to pretend to be a christian for her sake, but I don't think I could pull it off. I do wonder, though, if (hopefully) years from now if I am lying in my death bed and she is at my side, if the most loving thing to do would be to fake a conversion.
