Hi Dan, hope you are doing ok.
Remember, all those things that look so scary and uncomfortable are keeping mother comfortable. The sedation is amazing. People wake up after weeks of intensive care and have no memory at all! And then they look around at their family who are wrecked and hanging with nerves and exhaustion and wonder? "Gosh, what is up with them?!".
Do you expect her to recover? Sorry, if that sounds insensitive.
