I know what this is like. After John Ritter died, I was certain that I too had this missed heart condition. I hate reading or watching anything to do with health. I have to avoid it for now. I also spent a lot of hours searching for symptoms online and BOY can that ever scare the heck out of you. I think I've diagnosed myself with every major fatal illness out there! I owe $14,000 in unpaid medical bills just to be continually told I'm fine. This is truly a horrible condition. It impacts us emotionally, physically, financially, and our relationships. I don't allow myself to search for symptoms anymore and I've cancelled some of my upcoming doc appoints (I always schedule with two specialists in the same field in case one misses something), but now, I 've canceled them and have decided to only go if I something is bothering me to the point that it is impairing my function - which right now is only panic disorder that impairs me - not body sensations.
