I'm going to talk with my doctor more in depth about it this week, but, the possibility has been brought up that rather than unipolar depression, I might suffer from bipolar disorder. It's important to figure out which so we know what to treat.
Looking back, it seems like a pretty distinct possibility. I have bursts of significant happiness and productivity that almost always crash down hard. And with the way I currently see my mental state, I feel like that significant happy feeling is closer to what my baseline should be... so when I feel "normal" I still feel like I'm missing something? I dunno. I could of course be wrong.
