I have had anxiety since childhood and HA for the last 15 years or so. Although I did have HA before that but nowhere near as bad. Now this is how it works for me. If I am given medication..I read all the side effects and then panic! So, this made me stop taking the contraceptive pill as I was obsessed with blood clots. Luckily for me, I have never had an accidental pregnancy even though I only use the rhythm method!
This is another reason I have never taken medication for my anxiety as even those have side effects!
As for your heart anxiety...this one has happened to me in the last few years as one day I was out cycling and I could feel my heart racing and felt like it wasn't going to calm down. When I got home, my face was red and I felt really hot. Now that was it for me, no more cycling and then obsessed with my heart. One night I got a pain in my forearm and stupidly (I hate myself for it) I googled it and the first thing that came up was heart attack! Well that was it, massive panic attack that scared my husband and he nearly rang an ambulance.
After that, I kept noticing this forearm pain for ages but in reality, it was probably down to using my laptop! However, when I would walk uphill etc, I felt the pain in my forearm. I then started feeling an angina type pain and panicking about that as I would get jaw pain and a friend told me she had angina and her symptoms were jaw pain! I am terrible for listening to someone elses symptoms and then I start to experience them!
I then had a health check and for the first time ever, my BP was slightly raised. The Nurse took it three times but I told her that now I was panicking as she told me it was slightly raised. She then said it was nothing to worry about but to get it checked with Dr but instead, I had my friend check it on a home bp monitor and it was fine but then, I got obsessed with having high BP. I had it checked last year and although it was still slightly raised, it wasn't high and i felt a bit of relief but still, I panic over high BP and heart attacks.
To be honest, it is just yet another form of my HA which is really never ending. I try my best to rationalise and find keeping a diary of my symtoms is useful as then I can go back and see that nothing untoward happened to me the last time I had that symptom! In fact, I mentioned on here the other day that one particular symptom I have been getting for 16 years and nothing drastic has happened.
Although I always panic I have some health problem or other, I rarely go to the DR. On the rare occasions I do go, there is never anything wrong with me! I have never gone about my anxiety. Have never taken AD's or had any CBT.
I understand your panic but as your ECG's are clear it's obvious that you do not have a heart problem but your anxiety is hightened and I can fully understand that, but what you need to do is fight the anxiety and not let it win. Easier said than done of course.
I know google is not good for you but I find the website 'no more panic' a great help. I type the symptom I'm having into google then next to it ,no more panic and it will bring up people who have the same symptom on no more panic. It's amazing how many people are suffering the same HA as you at the time and I always find that reassuring and my anxiety soon fades (for the time being!).
I am not saying don't take the anxiety meds I'm just letting you know that it is possible to manage without them.
