Sam just couldn't deal that Dean had died, the way he died it was just wrong. Sam, couldn't help the fact that he knew he could've saved him, he knew that.
No matter how many others say it other wise. Dean might've wanted to go but in the long run Sam knew with all of his being that Dean wanted to stay. For Sam's sack, for his own sack.
His older brother was gone and he wasn't coming back any time soon. Sam tried the only thing he knew how to bring back the dead; the crossroads.
She rejected the idea of bringing back someone who would only kill more of her kind. So instead Sam killed her, sick and tired of no one wanting Dean to come back, of course though it was her, that evil son of a bitch killed Dean. Well almost, Sam knew what she did, she controlled someone else, just to shoot Dean.
Sam was right there he could've stopped the person from shooting him, he actions though were too slow. He knew Dean brought him back to life, he had one year. So why didn't he get to fully finish that one year, why was everything now finally on Sam's shoulders.
Everyone, everyone that Sam loved was now gone. His mother, Mary, he nearly had a wife, Jess, His father, John. They were all hard to live with the fact that they were gone, that they weren't coming back. But Dean, he was different. Dean always had Sam's back, when no one else would.
That was Dean for you, never giving up, no matter what. Sam knew he would eventually do the same, but for now the only comfort he would have was mourning. For every one he lost, he knew that his time would come too. Only ever though, too soon. In the end, he failed his only brother.
Note: I realised how long it looked so I split it up into sections. Anyways, still awaiting a review for this one :-p
