This thing keeps happening where I travel somewhere, do something really cool and exciting and energising... and then I get back and I spend a day or so as an emotional wreck, after which a horrible bone-deep fatigue sets in and I feel profoundly heavy and empty.
...Anyway. Found out today that this is an ADHD thing and there's even a name for it: ADHD crash, or dopamine crash. So that's neat. Although several other ADHDers in my life do not seem to experience it quite like this so iunno.
