Good news
Although i am not a doctor,i do love my wife and just the thought of having to face something like that makes me cringe!
I do agree that you have a ton of things to take care of and that you need to show your beloved one how much you care about her and that you are more than willing to share that burden, you would carry yourself if you could, but let me remind you that for the sake of you both it is Imperative that you look after yourself cos if you forget to do so, you might run out of energy and trigger a very subtle yet devastating process.
I really wish you all the best from the bottom of your heart
