Again, I didn't say you can't/shouldn't be bothered. But there's a difference in just "being bothered" by it and letting it keep you down. Also, as a Christian I know from studying the Bible that all of this is just temporary. It teaches that this world will, more often than not, be pretty crappy in many ways. It shouldn't be surprising to any Christian. The positive outlook for the future is in knowing that if you live life the right way, there is a much better future waiting for you afterward.

I'm not a preacher and I'm about as far from being a "perfect" Christian as one can be, but if anyone wants to discuss it, PM me and I'd be happy to talk about it.
