My aunts and uncles have said they will not help or cannot be bothered to take care of my grandparents,leaving it to me (a 23yo granddaughter) and my mother. We do not mind doing what we do, but in between work, school, cleaning our house and their house, we're exhausted.
Is there any reason why your grandparents can't hire a professional Caregiver to come in during the day so that your Aunt can get a good night sleep during the day either after her work shift or before her work shift?
