Prudie, I would try to look at the positive aspects of your situation. You have a job where you are able to work from home, so you still have a job, which is very much not the case at this time when so many have lost their livelihoods at a stroke. A woman I spoke to in the Tesco car park was in tears because her husband had lost his job and company car, and she was in despair at the situation her family was now in. Very upsetting to see, as I could not go near her to try to comfort her.
Also, as you are at home you're not exposed to the virus, certainly much much better off than all those poor souls commuting, say, the London Underground - can you imagine that twice a day?
Make sure you go out for exercise, and be glad that you have employment; that spring knows nothing about Covid - the land is greening and the birds are singing, in spite of the sadness all around us.
