I'm so sorry for you, this is never a good situation to be in. As for the TA situation, although your trip is booked I will stay on top of her to see if she can offer the better deal to your guests and also ask if there is anything she can do to adjust your trip as well. In the meantime grab a bowl of your favorite ice cream and a heating pad and watch a good chick-flick to keep your mind on other things. I hope everything works out with the TA situation and that another job comes your way that is even better!
