(((((((((((peridotgreen)))))))))))) I'm terribly sorry your family is suffering. Life is very fragile and one never knows what to expect. Maybe that is for the best. If we knew ahead of time the chalanges we would face we might not be able to bear it. I'm glad you have a brighter outlook for your Father than you did as a JW.
Your grandson has youth on his side. Hopefully, he will beat his health problems soon. He is loved by you and his family and that will help in fighting his illness. May your faith and good memories give you comfort.
