Sam's trauma is so overlooked

That poor man has been through so much but the show treats it like it's a joke half the time. They give him these gutwrenching sub-plots that would make a normal person go insane (which he did on several occasions), drag it on for like 2 episodes, then he's somehow completely fine again? The special children thing lasted for 5 seasons then we never talked about it again except for obscure references and flashbacks, the cage with lucifer, the whole soulless thing lasted six episodes plus his breakdown when the wall broke then he passes it off to cass like some baton and suddenly he's all sunshine and sprinkles again? When he got infected at the beginning of season 11, the gates of hell thing, the gadreel thing, the gunshot with the god gun, I mean this thing hurt God himself and he just walked it off like a stubbed toe. Even way at the beginning of the show, Jessica, the woman he loved, who he was going to propose to, who he imagined the rest of his life with, died and we never talk about it again except that one scene where he says he still misses her in season 15. His trauma is so brushed off and down played it's sickening.
