I know this wasn't directed at me, but I'd like to also answer. I think most people in unprogressive countries (for example, the Congo, the USA, Saudi Arabia, etc,) feel depressed, anxious, get easily addicted to things and so on, regardless of what they believe or don't believe. It is because of the general horrible society most people endure in these types of places.
I was born and raised a Christian to missionary parents. I was home schooled, read the whole Bible many times, I had to memorize a lot it, we were always praying and on our "spiritual guard" and all that. I understand for some people some religious beliefs can be comforting. And that is fine, so long as they know it really is just a belief. I wouldn't want to take anyone's comfort away if it helped them and didn't harm anyone else.
However, I care deeply about what is reality or as close as we can get to it. So I cannot accept anything as "real" or "truth" without good evidence for it. But I'm actually happier, at immense peace and more fulfilled and hopeful, than I ever was when I believed I had Jesus and the holy ghost within me. Although what one feels is not a good way to determine what is true and what is not. I have no belief in deities because no one can show they actually exist. If that happens, then I will accept whichever god and/or god's are shown to exist. Real easy.
While on a few occasions I am sad there is no perfect afterlife with our loved ones to be rewarded to us (although if you actually read holy books the afterlife talked about in them isn't very great). I am thrilled no one is going to be eternally tortured, punished with a possible ending to it, or in whichever way some writings say they will suffer. We can make heaven on Earth. That is what I try to do. We definitely have here and now.
