Until your cardiologist totally rules out your heart being the problem, I wouldn't assume it's anxiety. Your fortunate to have a doctor that isn't so quick to blame everything on anxiety. Plus, until YOU know for sure that your heart is fine, this fear will only feed your anxiety which will make it worse. I'm sure there is anxiety going on just from what you've described and now you've got the worry of your heart. You're very young to have heart problems, but it happens. I would also think by now your cardiologist would know one way or another if there is a problem, it shouldn't take this long. This makes me suspicious of his ability, I think I would seek a second opinion from another cardiologist (have all test results transferred) and see what he says. Right now you're in limbo which isn't helping you or your anxiety. People with anxiety do have symptoms like yours and often feel like they're having a heart attack, but you do need to rule out your heart. I truly think it's time for a second opinion on your heart, it's rediculous that he doesn't have an answer after all this time. I think once your hearet is ruled out as the problem your anxiety will become much better. Don't wait on this, you should be out there enjoying your sports and living your life. Get a second opinion regarding your heart and go from there. We're always here if you have any other questions, and we all know what anxiety can do to us. Take care.
Any responses would be appreciated, my standard of living just keeps on dropping and cannot shake this anxiety until i have this heart issue out of the way...has anyone experienced anything similiar???]
