I saw baby pictures of me and my passed grandparents

It’s made me feel a type of fomo I’ve never experienced cause not being able to have them growing up. I’m only 20 and hearing people talk about there grandparents makes me sad as it’s an experience I never got. Seeing the pictures broke something inside of me that’s hurting me like nothing before. It pains me that they never got to see who I became but it’s more painful that I can’t remember meeting them.
