You're right. Nothing capital here.

I might be reading it wrong, but this piece feels a bit like a disappointed love poem, since you mention a "you" that created a hole, and "the things you said". Possibly also secret or undeclared love, since you mention "the things I never said" and "screams I quelled".

But of course I might also be reading it wrong.

And I'm also wondering what this "oath I never kept" is about.
