Hey! I'm sorry for you loss. I know how you are feeling. My grandma passed away on april 1st 2006 and since then my family has just fallen apart. My grandpa passed before her and I know she missed him so I keep thinking well even though the family is apart shes happy. Maybe your grandpa really misses you grandma!! I can't tell you if time will help I'm not sure.. but use your family of friends for support and get together with them more often. They will be there for you, I promise
