A word for indescribable pain; melancholic longing?

"Have you ever experienced a brand-new feeling that welled up inside of your heart and filled you with indescribable pain?"

A quote from the English translation of Cowboy Bebop: The Movie. Two characters are discussing a sort of painful, melancholic longing, like love but perhaps a new feeling entirely.

The Portuguese word saudade seems close, but I am aware that it does not have an English counterpart.

Is there a word I haven't heard that fits this description?

Solution 1:

I think 'yearning' is what you're looking for, although I love 'saudade' myself. One of those words watered down by common misuse, but the definition of yearning is "1. deep longing, esp. when accompanied by tenderness or sadness."

Solution 2:

There are several adjectives often used for such emotional pain, including

pining - to feel great longing or desire; yearn and to mourn or grieve for

wrenching - causing great physical or mental suffering [also gut-wrenching]

aching - >feel intense sadness or compassion

Solution 3:

Two words come to my mind:

insurmountable - incapable of being surmounted, passed over, or overcome; insuperable.

overwhelming - overpowering; so great as to render resistance or opposition useless.
