Maybe I'm being naive, but maybe it was just a terrible misunderstanding. Can you hang onto that possibililty until Thursday? Now on Thursday if it turns out to be true, then you can deal with the fall-out then. But right now you possibly be worrying over something that was a commuication issue...

If you can't hold onto that idea can you call her? You're in a bad place now, and a phone call would be appropriate.

Take care. I'm so sorry you're going through this.
