Why do I feel horrible? On second thought, don't answer that

I can sleep in. (Although I didn't get to today, so that explains today's mood adequately.) Today my parents are providing free childcare and I can look forward to that for most of the next two and a half weeks. Not as much as we got before the pandemic, of course, but a hell of a lot more than I had when not visiting family, with the added benefit that it's with family. I continue to have a job that I like well enough and can be done remotely. I'm healthy. 

In many ways my daily life resembles a vacation. And yet, I'm grumpy and stressed way too much. How baffling, there must be something wrong with me, right?
