check in: hopefully it for May

May is Math and Wellness Month and I don't want to be thinking about
all this, so hopefully I've written enough notes down such that I feel
expurgiated—I don't have to keep obsessively thinking about the thing
if I can trust that I've written down enough notes that I can pick up
again in June when I'm healthier and less heartbroken
