If you have real fear of hell, I'd say you haven't fully left your belief behind. Maybe time for some introspection.

Ah , Hell. That totally contrived eternal horror created to keep the sinners in line . Continually threaten them with damnation, and heavily instilled guilt !

No fear here.

The short answer is: the same way you rid yourself of the fear of monsters as a child; by reminding yourself that it isn't real.

The long answer: even IF Hell is real, people don't go there, and even if they do, it's not what you've been told. Most of the imagery we associate with Hell come from political social control efforts, from Dante, from Heironymous Bosch, from the Puritans.

Hell only has one defining characteristic, and one target demographic. Angels who either joined the Luciferian rebellion or took no side were condemned to Hell. Which is simply a place devoid of the presence of God. Which, for beings whose very design makes them addicted and/or slaves to their own worship and adoration of God, is punishment enough. That's it. Just a dark emptiness where fallen Angels cannot feel the warm light of their addiction.

Everything else is a human construct designed to fear-monger the ignorant masses into obeying the social edicts of the Church, which was a legitimate international political force for hundreds of years.

In much the same way as I overcome my fear of being eaten by a giant half-tiger/half-fish monster with five hundred eyes and teeth made out of rusty fence-posts - it doesn't exist, so I'm not worried about it.

It is strictly a makebelieve place created by control freaks to manipulate people.

Your in Hell right now. Think about it.

I do not fear what I don't believe exists.
I know hell isn't real, so there's nothing to be afraid of.
