Longing.

I'm not sure, but it sounds like loneliness. :( Wanna talk about what you're feeling in more detail?

Kind of, but not quite.

Well, is that feeling still there?

We're here for you silver

Yes. I wonder, is there a word for it?

You could make one?

I'm doing research now. There's hypophrenia which is a feeling of sadness without a cause?

Monachopsis is the subtle but persistent feeling of being out of place?

Saudade is a rather fitting description of what you've descripted.
"The state of mind has subsequently become a "Portuguese way of life": a constant feeling of absence, the sadness of something that's missing, wishful longing for completeness or wholeness and the yearning for the return of that now gone, a desire for presence as opposed to absence"

Saudade, that is exactly right.

And sehnsucht

This song, the middle part, gives me the feeling.
