I am sorry to hear this, but just take everything in its time and don't get discouraged. I had my surgery at Presby and also saw Dr. Flood (endo) in the hospital. He was also very good. So, if you can't get hooked up with Schutta quickly enough, try to get an appointment with Dr. Flood. He is the same service and I liked him a lot too.
The team there will be very supportive of your plans to have surgery. But, you do have to get that blood sugar under better control or you are setting yourself up for some big risks and problems. It might take a little longer, but your blood sugar has to take priority now. Once it comes into better control, your body will be better prepared for everything that comes with and after surgery.
When you or your body is under stress, blood sugars tend to rise and it is very hard to get them to come under control. So, please don't forget that and try to keep an eye on your stress levels too. I know that's really hard with everything going on, but try to just keep yourself focused, on track and composed.
Keep the faith - and stay hopeful. You can do it!! And, yes - please do keep me posted.
