Pacified/Silence Bug

Hello, I was playing on DK (lvl 64) on Icecrown and I abandonned one of the last quests in DK line when I got teleported to Stormwind. Now im in Stormwind and I cant do anything. For example if I want to teleport to Ebon Hold i cant because im silenced and if I want to kill a mob I cant because im in
pacified mode. I dont know if it is bug or I am stupid but im asking for help. Thank you.

Why would you abandon it? It was just to go up to the king and talk to him, maybe you can open a ticket and ask the GMs to give you that quest or something..
