What are the parameters of your lockdown? In my area the worst we experienced just involved a lot of businesses closing but no restrictions on movement, so we built a COVID bubble of 2 other families and spend as much time as possible with them. If that isn’t an option, are you able to go on walks outdoors? If so I’d take that opportunity to go on long walks with friends, masked and 6ft apart if necessary. Or maybe you can get to know your neighbors in some way?

I’m not saying this doesn’t suck, all my suggestions suck, but maybe they can be enough to keep you going, hopefully
