As a depressive myself, I concur. Sounds like OP is one of us.
The key is finding coping strategies. I exercise every day and lift weights five days a week. That helps me tremendously. As far as exercise goes, you basically try everything until you figure out what you like and a routine that works for you. If your energy peaks at a particular time of day, that’s when you should plan to exercise. (For me it’s in the morning.)
I also read a lot of books.
Thing is, I don’t engage with people much, and that actually helps a lot with my mental health. I have one in-office day a week and that’s enough to fill up my social gauge.
