I have no fear of Hell, so there is nothing to overcome.

I lived through hell twice by the time I was 22.

Hey! Hell is a nice place ? what makes you fear it?

Keep telling yourself it's imaginary. That's what I did I did away with religious bs/god. Imaginary things can't hurt you. Ihave a family member imply that I would go to hell if I became an Catholic. I was raised baptist. Which I don't need either sects brain washing and started my journey of enlightenment. Finding peace for first time in one's life is liberating.

For me the fear wore off over time. It's hard to break the brainwashing but it happens eventually.

Never feared hell but your question does bring to mind the first devout Catholic I de-converted from the blackness of superstition back to the default position of atheist. Before I helped him escape a life based on superstition, he was tormented by a great fear of hell. He told me this fear often kept him up at night or awoke him in the middle of the night. After he de-converted (took me about 6 weeks to bring him back to reality), The fear of hell was no longer a part of his life. It think with time, you will will be able to loose the irrational fear. Just takes time.

The religion I was brought up in didn't believe that hell was a burning place of damnation, so I never had a fear of it. They taught that hell was just death, like falling asleep without dreams and no recollection. They taught a lot of other nonsense, though. The teaching that bothered me the most was that God was always watching me. When I finally chose to be an atheist, I was so relieved that God stopped watching me.
