I empathize. I had to cancel an appointment today due to asthmatic flare & 3:00 a.m. onset of sciatica. I wrote a "mychart" message to the doctor whom I have gone to for years and asked him to be please be gracious and drop the $100 fee for a days notice cancellation as there was no way i could come in today. I feel like he will understand. Bless you. It's hard when you don't know from one day to the next how you will feel. I am sorry it is so hard for you not to make your appointments. God Bless You!
