So, I thought to myself, "I may not feel this very often, but it's a vocabulary word that people might actually Use, so I'll put it on blogger!" This is quoted from Girlbomb:

Sarah said the other day that her friend was feeling "weltschmerz," and I asked what that was, and she said it was German for "world pain," or "world weariness" -- or, as Wikipedia says, "...[T]he feeling of sadness when thinking about the evils of the world." Also known as "awareness."
