This is not meant to be a suicide post!

Does anyone else constantly think about what happens when you die? I know it's morbid but it's something that's been bugging me. I want to believe that our spirits are released in to nature and that we become part of the beauty around us... But I also wonder about Heaven and Hell (I was brought up Catholic and have since discovered Buddhism and am currently studying it). Does anyone else think about this or am I just over analyzing life and death?
