I am having a very bad day yesterday, and as a result, I respectfully request that readers supply their own commentary for this post.
(It's nothing to worry about. I'll likely be fine by the time you read this.)
UPDATE: I in fact am fine. Disruptions in my sleep schedule are highly correlated to flare-ups of the ol' depression, and such a disruption happened yesterday morning.
Unfortunately, knowing that there is no rational basis for the way I'm feeling, and that it's all just a matter of me having gotten up too early, does absolutely nothing to blunt the unpleasantness. So I just have to ride it out for the 6-12 hours it lasts.
The good news is that my brain is extraordinarily predictable about the whole business, and there are certain subjects I only think about during these depressive episodes (Mostly prior employers and how badly we failed and disappointed one another, especially a job four jobs ago which I left in 2004 under traumatic and confusing circumstances.), which makes it much easier to identify what's going on and withdraw from the world until the storm has passed. Though experience is teaching me that I should be withdrawing much, much more thoroughly from Twitter when this is happening than I have so far been able to do. Something about how people are on Twitter really pushes my buttons sometimes.
