Sam,
So sorry to hear that...take all the time you need to focus on your family. We've got the fort held down here. My boss' wife had a terrible stroke a few years ago and while she miraculously survived it, she's so different now, it's extremely difficult to cope with at times. We're glad she's here but in a sense, she's not anymore. Just know that even if there is anything they can do to save him, it may not make things any easier for you all in the end. Sad but true.
Will keep you and your family in my thoughts.
