Encouragement?

I really need some encouragement please.

My husband’s father is visiting us and when I gave him the baby, it really hit me as if someone threw a brick at me. I felt very depressed and hopeless. My father passed away so I will never be able to experience how good of a grandfather he would have been to our son and I was a daddy’s girl.

Over the weekend we went to do groceries and his dad pushed the baby in the cart while my husband and I did groceries and I just wanted to breakdown. It really hurts knowing my father never will have this chance and I will never be able to see them together...
