That awareness makes you special. This is the only kind of thinking that will lead to progress. Someday maybe death will be beaten. Maybe lifespans will be extended, or maybe we'll figure out how to upload individual minds into greater technology than human bodies. Maybe we'll improve space travel to a point where we find something we never imagined. These are fantasies, but much more viable to me than theistic musings. Someone has to pave the way. You're not alone, so don't despair. Your ideas, when shared, cause a chain reaction. That makes you important to me, to other people like us, and to future generations.
Besides, comedy is fun. There are beautiful things happening all the time. Chin up, sugarplum!
