Awe, we do what we can for our parents when this happens. You're a good daughter for trying. I have helped my parents along the way too in their latter years but it was my paternal Grandmother where it was an extensive and more serious feat as she had demntia, deiabetes, and broke her hip, had various other illnesses such as arthritis in her back and gall bladder surgery, Shingles, one after the other. Whew! Most of the time she was not in the hospital but the trips back and forth sometimes were unnerving too. Her mind just wasn't her own anymore, she accused people of things, and forgot who I was, the normal sad things a person with dementia usually does. You just have to remember we all get that old eventually if we're lucky and it would be nice to have someone to take care of you too then like you're helping your dad. God Bless and may your dad live an even longer healthy life.
