specific story and general mean Dean

[wianea03.livejournal.com]

So I need to find a story and I know, almost positive it was on fanfiction.net. Here's what I know...

Dean got cursed and after John left him alone with Sam he turned really mean towards him.  I know he was like pushing him against the stairs and hitting him. He left him standing on the table with a noose around his neck and John came home and found him in time. Dean was cursed into doing this and they went to some lady who helped them and Sam had to shoot something.

Or if there are any other good stories where Dean is mean to Sam for some reason, any reason. It can be wincest or general. I like happy endings, like where Dean realizes it and feels guilty about it and makes it up to Sam, but it doesn't have to be.
