Your not crazy, just anxious and for whatever reason we search unwillingly for new things to worry about. After the 7 EKG's, stop worrying about your heart (I know that can be easier said then done.) I used to get bad heartburn, but started making sure I didn't eat anything for at least 3 hours before bed and it got much better. Additionally, alot of the information out there says excecise, weight, and caffeine can impact anxiety. I started walking every night for the last month and a half, lost 30 pounds in the process (have been dieting as well), and gave up the 6 sodas a day for spring water. In my case, I realized I had to help myself as well as try a med. If any of these apply to you, give them a shot.
