5 days before surgery

I'm in pure panic mode about the upcoming surgery. I have only 5 more days left to do so many things but I have rearranged my life for this and it's happening...well...
Nope, just kidding...it's not.
The boys and I had to run our lab mix to the vet for a surgery to get a large mass removed from his thyroid and my cellphone rings. It was Dr S's head secretary, Lauree. She's the one all the young little receptionists have to ask all their questions to. As soon as I heard her tone of voice I knew there was a problem. Lauree proceeds to tell me that the doctor has had another surgery scheduled longer than mine and its at another facility and he can't 'facility hop' the day of my surgery. I think to myself, 'OK, so it'll change a day or two...no biggie'. Then she continues to say that he feels strongly that I still have the nasal septum repair and turbinate surgery that my insurance company has denied as not medically necessary so he's continuing to appeal that denial. Then comes the date. September 18th. Oh. My. God. Anger cannot even begin to describe my feelings. I have literally put my life on hold for this. I have my leave of absence papers filed and approved at work, my actual work duties covered, babysitters arranged, hubby took off work, I've paid a whole bunch of bills early that would've been due when I was off and low on money- in turn putting us in a bit of a pinch for a couple weeks, and lastly had the consulting company that is working with our company schedule their next visit (from out of the state!- so airfare/hotels/etc) for when I would have returned from surgery - but now for when I will be gone. I'm beyond pissed off. Livid would be a better description.
Well, I guess I will make the most of this. I guess its good that the insurance authorization will be approved (hopefully) so I can have the entire surgery. I guess its good that I will be OK for K's first week of school. Now I can go to all the restaurants I've been wanting to eat at before I can't chew for months. I can learn the new system at work better before going out on leave. Its OK...right? Sigh. I guess it has to be, I have no choice.
