Long time lurker, first time poster. I've had anxiety for the last five or so years, beginning with much more frequent panic attacks that have settled into a pattern of relative happy calm punctuated by periods of intense obsessive anxiety, particularly concerning my heart. I'm 26, almost 27, have no family history of heart disease, resting HR is good, blood pressure is good (though, of course, prone to rise with anxiety), and I don't smoke. I have no idea what my cholesterol or anything else is, though it was fine when I last went to the doctor 4 years ago, but I'm overweight. I cannot stop thinking that I am going to have a heart attack/am having a heart attack/have already had a heart attack and just don't know it. I don't know how to stop obsessing about it. I live alone, 500 miles away from my family and everyone I know, so that's definitely part of my stress. I've scheduled a doctor's appointment next week, but I guess I just need to hear someone outside of my family tell me that anxiety lies, that obsessing over heart disease is a little irrational. I know this is often a big cause for concern with many anxiety sufferers, so I just wanted to know what gets you through it. Any help?
