Thanks for the advice guys, I couldn't tell you where I am because I'm completely new to the game. I'm near some tall buildings behind an army camp. I went exploring a building with a broken elevator shaft and broken stairway when I zombie hit me through a wall to an unaccessible area. Then I tried walking through walls and fell below the floor and have been stuck there since! I can't gripe though as it is Alpha, I just don't want to lose my items ha ha!
