all things work together?

so, right now i am thinking about how God works all things together for good. and i'm beginning to wonder if that is really possible. not that God isn't omnitient and omnipotent and all those other omni's, but does he really care enough about the little things that go wrong to make sure they come out good? and what about five year olds who die of cancer? i'm sure her parents are seeing the good in that situation. just getting a little pissed at well meaning people who spout triteness like its their job.okay, that was harsh. but i'm still frustrated.
