Put on some nice clothes, take your friends out to dinner and breathe deeply.
Now, call on the next available Wednesday around 2 in the afternoon.
Midweek, afternoon, and see how she is. Make her feel you are not pressuring her, and that you really appreciate her working on getting you another position. See how she is and ask her if she would like YOU to maybe look at the site and see what other positions are available and drop her an email with the ones you liked?
I am sure she was stressed to all beans that day having to disappoint you, and then the ordeal of trying to find another place for you on short notice.
A bit of time, and a call placed at a logically reduced stress time might just be the ticket.
Keep me updated!
PS. Don't forget to feel it out, this advice might sound good, on paper from here, but it might be bunk on that afternoon.
