Followup: I've now returned to work half-time – putting my retirement on hold for at least a year.
The half-time part is what made this something I was willing to do. Even so, it does mean I will be pausing or abandoning several personal projects I no longer have time for. But others will continue, and that's a good thing.
Still, I feel unsettled about all of this. I LIKED being retired.
