called in sick?????????

Today is my appt with my normal Dr for bloodwork, examine my lungs, ekg & all that good stuff to get clearance for my surgery. My appt has been set for 3 months now...I picked a female Dr that came highly recommended...as we have only lived here for a few months, this will be the first time I have met the Dr I picked out...so I was told my appt would be extensive...and first thing this morning I get a call saying my dr called in sick and would it be ok if I saw another dr, a male dr, in her practice...and if I couldn't or didn't want to I wouldnt be able to get in with my dr till the end of sept, and that is when my surgery is scheduled. So,..of course I have to say yes. I am already freaking nervous for this appt, and now to have to see a guy for this "extensive" appt. This is my last hurdle to jump before my surgery. I passed my physical therapist appt. I passed my nutrionist appt, I passed my psycholgical appt...all thats left is to get clearance from my dr for surgery...and I am nervous. I don't really know what to expect today, what all they will be checking or doing....I'm pretty healthy but I haven't had a real full checkup in forever, I usually only go to the dr if I'm sick...I don't like Dr's....I hope today goes quickly and good. I hope they don;t find something that stops this surgery from happening. I want it so bad!
