I have not become an atheist yet, but am certainly well on my way to being agnostic. Either way, having no hope for the future is more realistic and much less disconcerting for me, than having hope in a lie...which, once you realize it, is having no hope at all. What ever will be, will be. Local saying where I live: "If can, can. If no can, no can".
A positive outlook on life over rides dreadful expectations. Don't worry, be happy....be responsible, but be happy!
