Short answer is: I think I've been coping ok.
Slightly longer self pity crap answer:
I'm even more afraid of "outside" and people generally, but that's just a small incremental change- I've not left my flat for years anyway apart from essential shopping to Aldi or local corner shop once a week or so. I used to get 2 weeks food at a time, but now I'm struggling to carry a weeks worth, which sucks. It's only a few hundred yards away, but it's getting more and more difficult to carry stuff back. Legs get very wobbly and ache. I mostly buy the same crap every time- bacon, bread, and stuff for spag bols. Sometimes I get spuds and sausages instead. Yeah I eat the same crap all the time. I can't really cook, and it's not really important anyway. It's just cheap fuel. Anything nice would be wasted on me, or I'd cock it up trying to cook it, and I can't afford to do that, so..no risks. I do occasionally treat myself to some chocolate or cake, but always feel guilty. No teeth doesnt help either, but at least that means no more tooth ache. and the whole face mask thing I like. Hides my face.
I do have days when going out for food feels too much bother or too scary, but hunger usually stops that apathy after a day or two. I haven't been depressed, I don't think- but I can never really be sure of that until it gets really bad, and so far this year, it hasn't. Recently taken up chess, after not having played since I was a little 'un. Only against the computer or chess.com bots. Not against people, too scary.
I do miss my brother more and more though. He died 6 years ago now, and the pain of his passing feels more acute now than ever. The first thing I do every morning, and last thing at night is say "Ayup John or G'night John. It's just habit, and habits are pretty much all I have. Miss you John.
Don't know if I should remove this long answer crap. Might delete it later.
Sorry to have gone on so much, when everyone else is having much worse times. I hope you all find a little joy and peace.
