Setback?

Well, I had an appointment with my primary care Dr. today. We went over some of my recent test results. My thyroid levels seemed low?! Dammit! My heart rate has been elevated for some time now as well. So many test are scheduled. Ultrasound for the thyroid, stress echo for the heart, more blood work. I don't really care as long as everything comes back OK. If it shows a metabolic problem then surgery would be a no go. I would be ultimately discouraged. Soooo sad.
