Fish out of water
I would go to the most spectacular sites the city has to offer and while I am exploring I will be stopping in some small shops, trying to communicate with the townies, explaining my situation but all the while knowing that things will work out, no need to panic, take advantage of the situation! you don't have to argue with anyone about where to go or what to do, you're free to make your own choices! Eventually after you've seen what you needed to see, explored and wandered, find a small coffee shop, explain your situation as best you can and possibly get a free small coffee while you wait for the police or figure out how to get to the US embassy. Most like you will have solved your delima by then.
