You poor thing! You are a hard worker and you should give yourself credit for that. It’s hard to be divided between so much.
I know this is easier said than done, but focusing on one cleaning task at a time will help.
When I struggle to get motivated to clean, I set a timer for 15-20 minutes and tell myself I will work on cleaning until that timer goes off. I start with the more noticeable higher priority tasks. Usually the hardest part is getting started.
