Hey y'all,
I was hoping you might be able to point me in the direction of some fics.

I'm looking for fics where either Jared/Sam or Jensen/Dean are one another's mate and one of them hurts the other or rejects them in such a way that they get so heartbroken that they either get sick or are on the verge of dying...
Happy endings please and self-recs are always accepted.

A/B/O dynamics welcome, or even other creature fics too (i think I've seen dragon ones like this)

Please and thank you my friends!
