Laurel, how frustrating and scary this must be for you. At least you know you HAVE something wrong with you (although you knew that already) so you can focus on getting it fixed (and telling a bunch of people "I told you so!!").
I know what it is like to be waiting, terrified of what is coming next, but as Kitt sagely said, try and stay in the moment...you will drive yourself crazy worrying about "what could be". I really hope that things work out for you, March seems like a long way away (especially when in pain). Please keep posting and letting us all know what is going on.
(((((hugs)))))
