Not Stalgia

Nostalgia is derived from from Greek nostos ‘return home’ + algos ‘pain’.

Anticipated nostalgia is the expectation that one will feel nostalgic for a present or future experience in the future. It’s a cognitive process that can predict nostalgia after a significant life transition.

Yeah but what about feeling nostalgic for the future that hasn’t happened yet?

For example, you’re 60 years old and you’re anticipating that you might not ever meet your 6 year old son’s children.

We need a word for that because I feel that more than any emotions I may have about the past.
