Its stress. You need a break, even if you can’t tell you need one. I know, because I’m in the exact same boat, and I need a break too. You and I need physical rest, time to dissociate mentally with existing responsibilities, and spiritually (emotionally) reconnect with our motivations for living.

I think its reasonable to assume these symptoms are compounded by environmental factors (like having had covid, stress, getting older, etc), but ultimately, its our own behavior to be put at blame. That doesn’t preclude the need for potentially deep recovery. For example, I was extremely burnt out 6 years ago. I made a huge number of life changes, where I knew I would be overextending myself even further, with the goal of being able to real it back in at the end to a much more simple calmer life. And it would have worked if not for the complete and total collapse of American democracy.
