Stuck dead without spirit healer

I was on the quest “in the house of light and shadow” and died because of a bug or something after i clicked on the sword in my order hall which was a part of the quest. there is no way for me to get to my body now, and when i click “get back to graveyard” i get transportet to “chamber of the guardian” in dalaran, and there is no spirit healer there to bring me to life… i have spent many days on that character and would hate it if i would have to start over… is there anything i can do?
