AN AUTHOR'S NOTE
Okay, so the story ran away with me and I wrote the wills for Sam and Dean. The timeline should be right if Goodbye Stranger fits with real time.
Sam found Dean's will in his inside pocket, dotted with blood but he read it. Then he handed it to Castiel. This is one of the reasons Cas was still stood over Dean's ashes two days later.
Sam's will was in his hand when he died, along with a note that read:
Call this number. He's the only one who matters anymore and tell him, I'm sorry. Followed by Castiel's cell number.
Sam did not commit suicide; he simply yelled at the heavens until an angel appeared to kill him. He managed to overpower the angel and get his blade and kill him with it, but he was sloppy. Purposefully. He was stabbed in the chest in the process. He died from blood loss.
