rose,I can see why you would have so many reasons for your anxiety to be elevated and perhaps your heart rate was a little fast.
When is your surgery scheduled? You Dr. must clear you for surgery after all the pre-op tests are done so if nobody has called you to tell you that you cannot have surgery, try not to get stuck in "what if" thinking.
Hope by now you have heard from your Dr. and forgive me for not getting to your post until just now.
Kindly,
Kitt
