I am finding I have similar problems but less severe with long covid and shingles. I just don't have the energy or the clarity of thought to function as I should. It's 3am in the morning as I type this. Most nights my sleep pattern is so broken that I struggle to get three hours sleep without getting woken up by the pain in my left eye. Many things that were easy are now exhausting. I have been to my eldests birthday celebrations earlier this evening and when my youngest had driven me home I fell on the bed and didn't get up to wash and clean my teeth etc until two hours had passed by. It will pass and/or I will find a routine that allows me to cope better/
I understand how you feel.
I don't sleep well at night and then I don't want to get up in the morning.
My energy is way down which makes it hard when taking care of hubby.
I am now in week 27 with the shingles.
Hope you get better soon!
