Writers are lucky creatures. We can work from home, or from anywhere else in the world, so things like pandemics don't affect us much. Nor do shutdowns. We tend to be isolated creatures, too. But we do need some personal contact with other creatures, and one of the best ways to do that is to embark on projects that involve other writers, or to make an indie film.
I have the distinct pleasure of being involved with several "teams" of writers and film folks, so I get the joys of collaboration even in times of staying in your own house when possible. We can zoom, meet for lunch, and still keep things going, with a few tweaks here and there. Creativity and the urge to tell stories and share information never stops. So it's all about adapting.
Even if you have a more "normal" job or career, what are some ways you can adapt to working at home more? Seeing people over Zoom if you can't meet in the conference room? Working with partners or teams so you don't have to feel so alone?
I can do my job from a deserted island (if it has internet connection, that is) or in the middle of a busy city, and I realize how blessed I am. Look for ways to adapt to the current situations to make them work for you. All it takes a little resourcefulness and creativity.
