Post apocalyptic fic with thinks he's a burden sam
I remeber reading a fic a while ago that had a scenario where they stopped the apocalypse but sam was tortured by lucifer. Dean wakes up after being possessed by michael and thinks sam is dead because he isn't there. Bobby and cas are there and tell him that sam won't come home because he is trying to set dean free from himself. Dean calls him and convinces him to come home. The fic ends with sam on his way.
