Is there a word for mourning the loss of perceived potential?

This is probably an oddball question, but I was thinking of this. I know someone who just found out their child is developmentally disabled and they are struggling with this. They are having a hard time accepting that their dreams of having a doctor or lawyer in the family are dashed and they have to set a new lower bar of expectations. In some ways, I think they are mourning the loss of their dreams. In some ways, it seems like a small death.

I was thinking of other ways people mourn the loss of what might have been the future. In a small way, if you are pregnant and find out your child is a different gender than the one you are fantasizing about, you “lose” your dream child and have to accept the child who isn’t the way you imagined. When a teen gets rejected for their college of choice, they mourn the loss of their dream of going to that school. Even when a holiday is rained out you might mourn the loss of a beautiful day outside.

Is there a word for this condition? I think their should be.
