Thanks everyone who pitched in with advice for me when I was too stressed to think clearly. I asked my landlady for an extra two weeks and she kindly agreed. I'm so relieved. I did find a place to stay temporarily, but the woman called me "the right kind of people" and then tried to friend me on Facebook. That felt a little too intimate and possibly racist for my comfort. I'm glad to stay here where I feel safe for a couple of weeks.
