If you're worried about what happens after you die, worry no more, nothing happens! How do I know? Well, because your body dies! All of your energy will decompose and be sucked by the soil. I was raised a Christian, and I believed in the afterlife. I was concerned with going to hell, because no one wants that. But I was being fooled. Things were not making sense. The more I thought about it, the more I realized it was not true.
I started to listen to people I previously disagreed with and new thoughts entered my head. I started to notice how things in the Bible were not adding up. You can do your own research and find out. But you have to question the nature of everything in the Bible. Do not go with the mentality that it's correct because your brain will find a way making to make the nonsense make sense. Read as if you were reading any other book. If something doesn't make sense, it just doesn't make sense!
It's difficult to come out of religion. Specially when you were born into it. But you have to question everything that you believe in, and it should make sense. "God works in mysterious ways" is a cop-out. Things either make sense, or they don't. Don't be afraid of dying, it's the ultimate peace. Go about your life and be happy. Do the things that you enjoy because life is not forever.
