I am praying too. I understand what it is like, my baba is 87 and tough as nails. She cant walk any more, short term memory is gone, vision almost gone, but still sharp as a tack. The stuff you can learn from her is amazing! She remembers stuff from waaaay back. Love her deeply!
I pray your sister will get better real soon!
