I could sit around and wallow in despair for a while

But, well, let's not. The next time you feel like doing that (i.e., probably every hour or so for the next two weeks [years?]): take a deep breath, remember that you're not quite going to bear the brunt of it, look forward and think of what you can do to change things, look around you and listen and offer support to those who need it more, and act. And remember that in the shitstorm of rhetoric that's still flying around you, the truth, as always, lies somewhere in the hazy unarticulated middle, and that you would do well to listen carefully and discern the inside voices and subtle overtones hiding in the cacophony. (Of course, all of this will be moot if nuclear winter actually happens.)
