I know how extremely difficult it is to "cope and relax" when the issues are cardiac related. The best advice I can give you is simply don't give up until YOU are satisfied that everything that can be done HAS been done. Study your test results and ask questions about what you don't understand. (Which for me was virtually EVERYTHING) Write down your questions and concerns and take them with to your next appointment. If you don't understand the answer, ask the doctor to explain it in language you CAN understand. I very seldom recommend anyone Google health issues as that is the equivalent of entering the 7th Circle of Hell (and hypochondria) BUT……..there ARE two sites I highly recommend for excellent information that is completely accurate, up to date and written in such a way that lay people can understand. The Mayo Clinic and The Cleveland Clinic. Both sites will give you excellent advice about what to discuss with your doctor. I truly believe you're going to be just fine, and whatever you need to do to "cope and relax" until you see your cardio again, DO IT!
