Read a book. I find when I am in a funk like this I have not desire to read, even though I love reading. I have forced myself to read the last couple of days and it really helped. I read a book Friday and started another this morning, though going a bit slower.
Oh and for the love of god put down the phone. It is too easy to scan your news feeds and get dragged down. I actually deleted Google News off my phone until this passes (and it will).
Sleep is the hard one. I have been keeping myself pretty regimented, getting up at my normal time even though I am working from home (with about 2hrs worth of work a day). Naps can be the worst. I am an introvert, but I need social contact. The hardest part is keeping your brain buzzing and thinking instead of letting it run on autopilot. Take care
If the sun comes out again, get outside.
