(((Amanda))) that's my worst nightmare. I hope you find her soon. Maybe notify all the local vets and put fliers there as well. Also, leave food and water out for her.
I had a friend when I lived in NYC whose cat escaped her apartment while she was in India. She returned home on the next flight, since she didn't trust her cat sitter to find her. It took a couple of days, but she found her in the basement of a neighboring building, in the East Village. So, don't lose hope.
