I know what it's like to be in a situation like this. My grandpa died to cancer and my grandma was diagnosed with a tumor in her brain. Good thing that it hasn't grown in 3 years but it keeps everyone in the family worried. I'll keep Don in my prayers and thank you for being such a supporting friend. Keep us posted on his health status.
We're all praying hard for you and Dom. And we'd better pray for his wife and kids too. I've been through the 'Relative in intensive care' trauma, and knowing that people pray for you helps.
Everyone is in my thoughts and prayers as well... I've been through this many times in the past few years with family. It's a tough experience, but just knowing you have people to support you is priceless! Please keep us updated.
