Not sure what the word is. But this sense of searching for words to describe complex emotional experiences….you gotta check out Dictionary of Obscure Sorrows. Dude wrote a whole dictionary inventing words for many of these complex emotional states. The words sound and seem like they could be real, drawn from etymologies in different cultures. Definitely a lot of Japanese influence. Also, the definitions themselves are sublime. A lot like the paragraph you wrote trying to get at moments that would encapsulate that emotion. I hope you give it a gander. I give it as a gift multiple times a year and the people I share it with just love it.

Added to my list as well! This sounds *right* up my alley.

Edit; oh man, happy New Year!
