I think that the only way to deal with it is to tell yourself that every government in the world will have their top experts working on finding a solution as quickly as possible and that they’ll be doing everything they can.
Stay away from social media for a while, unless it’s watching live cams of zoo animals, or screenings of operas or plays etc. You can even take a virtual tour of the Palace of Versailles. Think about the first thing you’ll do when you’re able to. For me, it’ll be sitting on the beach with an ice cream (even if it’s snowing!). For DH, it’ll be having breakfast at his favourite cafe. Are you in a position to check on elderly neighbours without putting yourself at risk? Occupy yourself as much as possible.
The experts are saying that these things often come in waves, so don’t think everything is getting back to normal because we’ve had a couple of good days but, equally, don’t panic if another wave happens. They’ve predicted this may well happen and are expecting it. Make sure you listen to the official advice and comply with it, but ignore tales of ‘my mate’s in the army and they say...’
I think it’s going to be a while until things get back to normal, if they ever do. But if they don’t, there will be a new normal, and that will be fine too, once we get used to it.
