Sometimes everything goes wrong in a self-defense incident. Stay focused. Stop the threat and keep doing what you need to do to get help. Remember, if a subject surrenders and runs away, let him run. Continue on your way to a position of tactical advantage and eventual safety.
You could at least know you didnt stand there and do nothing while a looney toon is trying to victimize you.
