Hi Sweetie, I can feel your pain:
First I need to know if you believe in God, because right now that's who you will need!! My husband was diagnois with pancreactic cancer two yrs. ago, at the time he was given a yr. according to the doctors. But just as I told the doctor's no one has an expiration date on my husband only God.
Being a Caregiver or a loved one to someone with cancer is not by any means an easy thing. rely on the the fact that you were given your grandfather someone who you had a chance to love, care for him and pray and trust God to do what is right: Sometimes what God chooses is right we won't agree with, but believe me he does know.
