Oh Tina, what a sad journey to be going on. It is such an awful time when someone close is so ill I know. Most of the people I have been close to have gone now, My Aunt May, my favourite Aunt Rose with cancer, my Mum with cancer, my husband with renal failure, and also my Grandad but at the ripe old age of 92!
I am certain you are right about your Rob being scared and upset, it is a hard thing to have to deal with.
I will keep you all in my thoughts and prayers. Hugs and love.
Chris
