Yes I have had Health Anxiety for 3 years and just like Debi I have gone through many, many tests. I worry about my health so much because I ultimately worry about dying. I am most fearful of the things that can kill me( heart attack, anuerysm, blood clots) not things like having the flu or a cold. If I have a symptom that I can credit to being something thats not serious than I am not bothered. Its as soon as I have a symptom/symtoms that I think could be something more serious than I am panicking. I break this cycle though by quickly trying to give myself an alternate reason for the symptoms I feel. Like if I have a headache I try to think of all the other reasons I could be having it like feeling tired or sore neck instead of thinking its an anerysm. If I can do this quickly enough than many times I break my cycle. I have also used the 10 questions to challenge my thoughts. Hope this helps.
