Character blocked from hearthstoning or accepting an instance que portal

My level 14 Priest is stuck in Stratholme! I was on my way to the zone north of Stratholme and I had the urge to visit the instance. Little did I know that the instance requires level 15 to enter. For some reason my character was pulled in to an instance that looks just like stratholme with no mobs or anything like an exit portal or much space to move and I keep getting reloaded in to the instance. The cool thing is that I discovered I can que and receive a battleground pop but I cannot take the portal from it to escape. The character was fun to level so I am sad that I will have to boost to relieve my character of the distress it is causing me. Lesson learned not to attempt to enter high level instances prematurely.!
