I am extremely hyper-vigilant about my heart (no idea why) but I can't take it anymore. I have been to my regular Physician many many many times and 6 years ago, I was diagnosed with severe anxiety and panic attack disorders. I have had numerous EKG's, halter monitors (24 hour ones and once one I had to wear for a month), blood tests, chest xrays, etc. I have recently gone to see a cardiologist to get some answers and he told me I was perfectly healthy. Even hearing a doctor who specializes in Cardiology didn't help. Nothing is helping me - I'm actually going to have an echocardiogram done tomorrow morning and even feel like I won't make it until then because today, when I was trying to fall asleep, I get woken up to this feeling of my heart skipping a beat. What will it take to make this all stop? I'm sick of feeling like I'm constantly checking my pulse and feeling like I'm going to die. Even when my TMJ flares up, I convince myself I'm having a heart attack! Someone help me end this vicious cycle!
