Not-depression

I still keep introspecting about what, if anything, is up with my brain. I recently had a bit of a slump in my current work project, several weeks of knowing what I needed to do and it was fairly simple, but not actually knuckling down to it. And that sort of spilled over to a general malaise. But, as best as I can tell from the inside, that's basically how I used to be *most* of the time. And when I have tasks I actually do achieve, I'm mostly fine, even more-content-than-average, maybe. But I don't know how to describe that -- it doesn't sound like depression as such, if I'm able to snap myself out of it *at all* -- but I feel like perennially feeling dispirited, whether or not it's just who I am, feels like a problem of *some* sort.

I should read over some of my old angst-y posts, I think my overall self-perception has become much, much less gloomy over time, but occasional bouts of introspection appear to be part of that.
