Funnydream .....
My first brain surgery (for trigeminal neuralgia) had to be pushed back a week because as I was being prepped for surgery (already admitted), I failed their bleeding time test (had stopped my Aspirin 6 days before, but apparently it was not long enough). It was truly a bummer of an experience ..... not only from an emotional standpoint but financial. We live several hours from where the surgery took place, so it meant two trips and much rearranging of work schedules, etc. When getting ready for the AN surgery, I followed instructions to the letter and all went off without a hitch.
You are taking it much better than I did. If you believe in divine intervention, the delay usually means there were very good reasons for it.
Best thoughts and many prayers for peace of mind between now and the 22nd!
