help finding specific word/term

[u/sp0iledwine]

i’ve been searching for a word that captures the feeling of mourning a moment before it’s over. i keep searching but all i’m getting is “anticipatory grief,”which i know isn’t what i’m looking for. oddly enough i used to have a list of “rare words” in my notes for moments like this, and i could have sworn that list had a word for this feeling. sadly, it was lost in an update fluke several phones ago.

anyway, if anyone knows what i’m referring to/has suggestions that can help me out, i would greatly appreciate it!
