Writing through a COVID winter

I've heard folks suggest that the combination of this brutally cold winter and the never-ending COVID protocols should be good for writers (as in, 'there's nowhere to go and nothing else to do so you have lots of time to write'). Sad to say it ain't necessarily so. The prolonged cold temperatures and the fear of getting sick are depressing. No one writes well when they are depressed. On the brighter side, Spring is coming . . . it is coming, right?
