Its a big shift and doesnt suit everyone so dont be hard on yourself Prudie. I'm hopeless at WFH, I get down, I cant concentrate and I resent work intruding on my home space.
Sometimes I put some music on, or the radio an make the room feel a bit more occupied. Take regular breaks, drink plenty and keep hydrated. And then go for a walk and remember that it wont be forever. We are lucky to have jobs, we're safe in our homes and not stranded abroad, and hopefully virus free. Its tough WFH but its really just the same issue of isolation thats effecting many people at the moment. Keep going and stay safe.
