Not necessarily. I definitely go through waves like this, and it doesn’t feel like depression to me.
I’ll have a couple of days (or weeks) where I want to do things, but not enough to actually motivate myself to start any of it. Then I’ll bounce back for a while and be so focused on something that I’ll forget about taking care of basic needs like eating and sleeping.
I’ve kinda learned to embrace those extremes. What I hate is the middle ground where I want to focus and get something done, but I realize about every 5 minutes that my brain is off topic again.
Pretty sure that’s from “I Second that Emotion”.
Bender flushes Nibbler down the toilet, but the Professor fits him with a chip that makes him feel Leela’s emotions. So they head to the sewers to find Nibbler.
