I've been feeling a lot better today. I'd even be willing to say that the worst is probably over—I've moved from an emotional apocalypse to simply depressed. I imagine this state will last quite some time, but I seem to be a functional human being again, which is a nice change. I'd still certainly say that I feel pretty awful, but I'm in a wildly different place than I was just three days ago.
I've been rather snippy recently, which is unfortunate. I've also noticed that I'm driving a bit more aggressively—perhaps from "drives like a grandma" to "drives like a middle-aged aunt." Both of those things should pass.
