Looking for a missing fic

It was a long time ago and i don't remember the title but the pieces i remembered is Dean saving Castiel from something and in his pain, Castiel accidentally revealed that Dean had tortured him when he was in hell. I think Castiel begging Dean that he doesn't have to do that anymore because he was there to save him or something. Ring a bell? Thanks in advance. :)
