I am struggling a bit, so you have my sympathies.
The thing that has helped me is to create a routine where there is no real routine, but that is possibly a bit easier for me as I am still working as a lecturer, so having video classes/meetings every day.
My routine is:
Get up, check emails, breakfast, shower and dress in nice clothes, put makeup on, do hair, clean teeth
Work until lunchtime, then sit and eat lunch at the table with DP who is also at home
About 3pm we have a cafetiere of coffee and a biscuit. Usually we drink tea at home, so this feels like a treat.
Finish work at 5ish, then go for a walk on my own
Eat dinner at 7ish. Do any house chores that need doing.
9pm we are working our way through a boxset, one episode each night. Once that's done, I usually have a glass of wine and read for a bit, then bed.
I'm also trying to connect with one person each day outside work/DP. Yesterday I wrote a letter to a friend, which I will post on today's walk, but it might be a message exchange, or an email - I don't like video calls outside work. I'm also keeping in touch with my neighbours, both of whom are lone parents - our cat is sending the children messages and little gifts like comics and sweeties.
Take care, OP, this is a shitty time.
