I'm not going to say sorry for your loss because I'm sure you're sorry enough for the both of us, and it's annoying to hear that. I would know, that's all anyone said to me when my Dad died this year.
But I'll just say, I hope you find a way to heal from it.
God will take care of your grandpa in Heaven, I'm sure of it, and my brother will be there to guide him. <3
I never really knew my grandparents. One died I think before I was born, and the other I knew as a really young kid, but he died and I don't remember anything about him. :(
I'll keep him and you and your family in my thoughts and prayers.
