Dead and Stuck in Dalaran

While playing, I encountered a game-breaking glitch that prevents me from playing the game. I'll start from the beginning. I was running heroic Halls of Reflection from RDF. Our group kept on wiping so we decided to kick each other to disband. I was kicked while I was dead, so I just flew up to the dungeon entrance so that I could revive and port out. When I entered the dungeon the screen was glitched and frozen, forcing me to alt+f4 and relaunch the game. Once I logged back in, I was still dead but somehow I was in the middle of Dalaran. This is strange because this was not where I was when I accepted the dungeon queue, and it wasn't where my hearthstone was set, so why did it put me in Dalaran? I soon discovered that since I was dead, I could not use the flight master or any portals, so I was completely stuck. If I could somehow jump off of Dalaran then I could run to HoR and revive my character. But there are walls all around Dalaran preventing me from doing this. Long story short: I died, dungeon glitched, and now I have no way of getting back to the dungeon entrance to claim my corpse. My character's name is Kyrne, on the server Icecrown. I hope a GM or someone can help because this glitch is preventing me from doing absolutely anything in the game. Thank you.
