I've had the worst fluctuations in motivation today - in the past few hours a revived obsession took me from "I'm going to accomplish all the things!" To "Why bother even trying?" I have no idea how I will feel tomorrow.

Also, does anyone here ever experience this kind of...hollow calm? Like you've momentarily pulled out of your depression, maybe have a burst not motivation... but despite how good you feel those pleasant feelings feel like a mask that's simply been placed over you by some unseen force? It's usual an rather unstable pleasure, like it could fall apart any second and plunge you back down? Because that's what I felt today.
