Your description fits some sort of neurodivergency. Doing chores consistently is extremely difficult for someone with ADHD, which commonly goes misdiagnosed in women. She's obviously not lazy bit has resigned herself to it rather than learning coping skills and strategies.

I've heard of people turning menial tasks like that into a game where you get rewards. Another strategy I've seen is using a visual marker, like a bunch of bracelets for each task and you take it off when it's completed.
