Get outside and get some fresh air, if possible.
I just rec'd a power washer and winter is winding down, so I think I will putter around with outside brickwork.
Very, very important to get UV light and not stay cooped up, if possible.
Also, diet with a variety of foods.
The most important thing, of course, is toilet paper.
If you have plenty of toilet paper, you are a winner!
Stay well.
