Just remember those people are your parents and
all they have sacrificed for you.
Yes, I have issues with my own father with dementia (He says he's "demented".) living with my family at this time. We have trouble getting him to bathe, he eats food directly from the serving dishes (and then it's all "his") and several other issues you'd have with a 5yr old...but that is the thing I need to remember, too. He has stood by me for most of my life and I am grateful for that.
