Sorry to hear it mate, all the best and stay strong for your misses.
It is tough as Fenster says better than a drawn out one, mine went from lung cancer a couple of years back it was so slow, bed ridden for months and my poor misses driving 200 ks back and forth twice a week to stay with him for 2 day stints and although she was there for him and her other sister is a surgical nurse he wouldnt allow them to help him (with drugs) till the last day when he had no say in it. It took a toll on the ones left but there wasnt anything left unsaid, so that the one good thing from it all.
Take care.
