In my experience, most of us who formerly had very active lives, also didn't get the amount and level of sleep we needed.
So now's the time to cancel your 'sleep debt', because it will all come to a halt one day.
I agree with most posts above which say 'don't feel guilty' allow yourself to enjoy the leisure which you sometimes longed for when you were working and exhausted.
Sorting out cupboards can wait; pick up a good book or watch TV, listen to music, pamper yourself a bit.
Tell yourself these are the GOOD things about being forced to stay at home.
I've just given you permission!
