Update on My Grandpa

My grandpa flat-lined last night. The worst part is that after they brought him back to life, he told them NOT to call and tell his family. I'm not sure how my uncle found out while he visited my grandpa today. He now has an external pace-maker. The thought of losing him scares me. He is the glue of the family for my grandma, uncle and aunt. Praying hard... I need a drink.
