I'm sorry for your friend's loss. I will be praying for him. You are a good friend to him. Just being there and helping him with his self-care is perfect.
Each of my parents has had life threatening illnesses and I dread the day I lose either one of them. My grandfather passed away a few months ago and even though he was 80 and had a full life my mom has had a very hard time with it. It's never easy but there is at least some consolation when they die in old age. I find if you don't think of them as "gone" but always with you in your heart and thoughts that is tremendously comforting.
I really feel for your friend's mom, she really needed her husband right now. I will pray for her as well.
