Thank-you Michaela, John, Natalie, Paula, Andrea, and Beth for all your best wishes and prayers (hope I haven't missed thanking anyone).
I spent about 5 hours with my Grandpa last evening, and then he passed away in the night with my mother (his daughter), by his side. No one thought he would go that fast, but he is pain free and in heaven with Grandma now.
Thanks again everyone for your support!
Peace be with you
