We are all struggling, religious or atheists.
, Jesus talks about Hell hardly at all and says he came to save sinners, reserves his opprobrium for those who don't help, eg Dives or those who hurt children. Even then repentance is possible,think of his companions on the cross. If you are trying your best, God is understanding. Jesus didn't have things the way he wanted them always, he had to take the chalice that was given him and he was miserable about it, even though he accepted it.
Tbh, I'm glad for people who are always happy, but Job wasn't, Jesus wasn't, the psalmists were often despairing.
I can quite see why it would be a terrible experience, especially if family, social life or other reliance were based in that community.
But read Job, because that's kind of what they said to him. And he survived and God supported him in ways that would have been comprehensible to his peers in the end. ( he got more cows.).
I think you can give up on them, but don't give up on love. And if you don't give up on love, in times when you feel like it and times when you don't, that's all anyone can ask.
I can't recall of which mediaeval sinner it was said
Mercy I asked, I mercy found, betwixt the stirrup and the ground.
We don't know what happens, we can only trust and do our best, be sorry for our deliberate errors, and act with love.
