Dianna,
sorry to hear about your condition. You said that you passed the stress
test with flying colors, but we have to remmember the old saying
about "it sounds too good to be true...". You need to understand that
there are no "bad" stress test results. This is part of the medical
profession and your cardiologist is just doing his job lying to you (no
leaky valves, normal echo, etc).
If there was something wrong physically with you, how would they
justify that you have a chemical dysfunction in your brain (the usual
explanation of the psychiatrists for the so called "anxiety")?
I suggest that you start writing a journal with your symptoms and
share them with a supportive group of friends that believe that you do
have physical symptoms. If they don't believe you, go and test
your c-reactive protein (crp) and show your results. Good luck!
Ps: you don't have to go back confronting your cardio b/c they work
with a double set of medical records.
