It's easy to get overwhelmed thinking about the things out of our control, that we can't do anything about. But we can remember that we are all in this together. The entire world is trying to deal with extraordinary circumstances. You are not alone. *Hugs*
A lot of stress comes with that, of course. It's ok to feel overwhelmed or even depressed about the way things are right now. Give yourself a break.
One way to look at things, though, is that we have one mission now, just one (pretty important and noble) job to focus on: preventing the virus from spreading to the more vulnerable parts of our population, by keeping to our own little bubbles.
Kinda like those living in extended isolation in places like the international space station or Antarctica, we can try to keep our minds on the mission. Set up daily routines and structures which help to reassure. Break problems down into smaller parts. Focus on the present rather than looking to a bleak future. Keep informed, but try not to obsess over numbers and projections. Relax the usual rules if you need to, in order to cope.
Maybe ask yourself: what can l do right now to make things a little bit easier for myself and my family?
Just my opinion, but I think it helps put things into a more manageable perspective.
