This reminds me a lot of myself. Since June I have been to my PCP and the ER countless times. I have had EKG's, chest X-rays, & electrocardiogram done along with blood work. I have been declared "normal" and labeled with anxiety. I obsessed that I was having a heart attack for 2 1/2 months. I obviously have never had a heart attack but I believe I know what one feels like because of my terrifying symptoms. Chest pain, arm pain, jaw pain, heart palpitations, just feeling like death is near. I'm a hypochondriac. But unfortunately no one in my life understands me... They just think I am crazy. I think I am dying 365 days a year. I am on medication with no successfulness. I feel your agony....
