I can't imagine how hard this could be for you and yours. Sounds like the bond between you two is like me and my dad. I'll make you a deal, I pray for my dads health and well being every night, and now I'll put you, your dad and your fanily in there too. Kepp your head high, it'll make him feel better. If he's improving so fast thats a good sign. Good luck with everything and God bless!
