Thank you for your post and I'm really glad that you've asked these questions - I know a lot of people are in the exact same boat as yourself. It's so hard dealing with the uncertainty of everything.
While I'm personally not working at the moment (no job beforehand :( ), I can very much relate to missing the routine and the feeling of not doing enough at home. It's also not easy when you can be surrounded by people who seem much more productive and busy!
What do you think is causing you the most anxiety right now? Is it the idea that you didn't do enough or didn't get things done?
One thing I think worth reminding myself - and you too - is that this is a crisis. It isn't just taking time at home and having time off. This is different. So it's okay if things are different at home too. You don't owe anyone anything and you don't have to be busy and do all the things, it's quite okay to give yourself some permission to rest.
I read a quote yesterday and I won't post all of it but there was one bit that said 'Trying to be perfect during a pandemic is like trying to stay dry in a hurricane'.
I hope this post gives you a little bit of comfort, or maybe a little bit of permission to take the pressure off for a while (or just a minute).
