The troll that beat you up looks like he's bleeding where you headbutted him––good. He speaks to you and you hardly even hear him over the roar of adrenalines and general stress hormones. You can hear your heartbeat in your throat, and you give a weak snarl that isn't very intimidating because you never learned how to be intimidating. In fact, you really don't want to fight. The urge to run away is overwhelming, and you're getting a horrible, choking feeling of panic because you're already lost and you're surrounded by humans and there is nowhere to go. 

You stand up as quickly as you can. "Shoo," you grunt.
