Truly sorry to hear about the troubles, but it is nice to hear that both are doing better now.
You have both our best wishes and positive thoughts as well!
If it's any consolation my Nana had a series of Strokes spanning a decade and well never really suffered from them in comparison to what can happen. So I'm hope that you Grandma is at least as resilient as my Nana was, if not more so
Big Hugs and as they say Chin Up!
