I have a kid graduating this year, and another next year.
I have already had 2 graduate.
It's rough. I cry too. I don't want my kids to leave. I want them to stay little so I can make them food, watch movies at home with them, take care of them when they are sick, etc.
My kids who graduated both are at college. They come home briefly throughout the year, and it is such fun to have them home.
It's one of those transitions in life we must face.
Cry and be sad, but be happy, too.
