Say what the promise was really about.
She was not asking you to do every task yourself. She was asking not to be sent away from her home, her things, and her routines. Being cared for at home, by people who show up, keeps that promise.
Doing it all alone was never part of the deal.
The appointments, the laundry, the nights. When one person carries everything, the relationship becomes the work. Help with the everyday gives you back the part of the day that is just the two of you.

Let her have a say in who helps.
Her home stays hers. Meeting a caregiver before care begins, and starting with something small, keeps the decision with her.
Give yourself the care you give her.
Sleep. Your own appointments. Your own family. Getting help is not the opposite of the promise. It is how you keep it for years instead of months.
At Pink Glove, that is the work.
Familiar faces, a coordinator who answers, and updates that keep you close. You stay her daughter. We help carry the care.
