Well the energy that you hold into your body will be released to wherever your body is, then it's gonna be reused for the planet's benefit, our atoms will literally never die, Lavousier once said, in the nature nothing is created or gets lost, everything is transformed, one day all our atoms is going to be swallowed by the sun at somepoint of the story of the universe.
If you worry about hell, the Bible is a book written in the metal age, about the thoughts of an ancient people who lived very specifically around the Mesopotomic area, where today is Iraq, if it weren't for the Roman Catholics who imposed religion throughout Europe and then in all their respective colonies, we might believe in the gods of nature as our indigenous ancestors.
And even if you want to believe the Bible, it says only 2 or 3 times about hell, and never mentions eternal suffering with fire, but said that we would be consumed by fire, instantly, which is like some derivations of Christian churches like those Jehovah's witnesses believe. The hell as an eternal punishment was described in other literatures like Dante's hell in Divine Comedy, written in 14th century. In the end, what matters and where we are all going after this life is all a matter of belief. I like to think if there's really a hell, I'm already on it, so after leaving this place I should find my redemption.
