This is the way I look at handling disappointments. I know its very hard when someone who's young and good dies at a young age. My own father passed away when I was 2 and left 5 children at the age of 34. I often wondered why would God take my father when he was needed by his children and wife. Even babies and children die - I think some religions think God is a punishing God - so when we suffer a disappointment, we think "God must be getting even with someone" or we look for reasons why. The fact is, we can't find a reasonable answer why a young person dies - it just happens and when you think of it, they're in a better place.

I don't think its fair just to love or believe in God when good things happen. God also isn't taking those we love to punish us, so therefore we shouldn't lose confidence. Some religions also give the indirect message that if we're good, then nice things will happen and sometimes they do. Unfortunately bad things also happen to good people too. In addition, I've found bad experiences have lessons in them and sometimes good can come out of bad experiences. I hope this helps.
