Wow, that is horrible! Your grandmother deserves to be treated and cared for with respect and dignity. I would have been livid as well. :-( I'm glad your grandma is back home again.
I had my dad at home for 1 1/2 years and it was one of the most challenging times of my life, but I am grateful we could keep him home for as long as possible. I was very fortunate to find a small facility for him with a caring nursing staff. One of our old aides works there too which has helped a lot.
I hope home health care goes well. Reliable and compassionate aides can be invaluable.
Take care, Pax.
