Hello!

Specific Request:
I read this fic a while ago, and I can't for the life of me find it. I'm a little unsure on some of the details, so I apologize if this is disjointed! It was something like: Sam was sent to another universe where he died in the nursery with Mary, but I think John lived. The Dean of this world is super lonely and depressed, blaming himself for his brothers death, or something. Sam tries to get to know him by saying he's his cousin, and they go out a couple of times. Dean eventually catches on, and is hurt. I believe Missouri is in this fic. In the very end AU!Dean dies. I think Sam goes back to his universe after? I don't remember if non-AU!Dean is alive.

General Request:
I just want the most heartbreaking Dean!Fics out there. I don't care what happens, I just want to cry my eyes out. I don't mind slash. Smut isn't necessary at all, but if there is some I prefer bottom!Dean, please.

Thank you!
