Strengthen your non belief I guess. That helped me. I wasn't exactly raised in a strict religion but I have had people around with very firm beliefs- including that suicides go to hell. When I first had suicidal thoughts- aged 10, they frightened me- in part because of this. It didn't take long though to realise that these beliefs weren't actually mine.
As I aged, I became more and more doubtful about orthodox religions. It made sense why certain religious ideas were popularised at certain times- including the idea of suicides going to hell. I wish I could find the YouTube video I saw ages ago... But yeah, it makes a lot of sense to me that religion is another tool for the ruling classes to keep the rest of us in order. They can't have their assets- in the form of their wage slave workforce killing themselves all over the place.
Honestly, some fear still remains for me. It's hard to get over it completely but, it's less than it was.
