Health anxiety / heart

Hi all, I’m a 26 year old male.
I have been suffering from a heart palpitations, it races, pounds and skips beats throughout the day.
It started in December and is still happening. I’m constantly thinking about it, checking my pulse, worrying always.
I had a bad case of C-Diff, which hasn’t helped. I am still recovering from it on antibiotics.
I have had over 10 EKG tests in the last 2 month alone, an echo scan, several blood tests and plenty doctors listen to my heart. The doctors found nothing wrong other than it going really fast.
But I still can’t stop thinking there is something wrong with my health, my heart.
Do others experience the same issue? I can see my heart pounding constantly.
I started 30mg of Proponanlol which has helped me to sleep again, however I still feel like my heart is pounding, fluttering etc.
I am also on day 13 of Sertraline.
All day everyday all I can think about is my heart, health and I can’t seem to stop.
It’s so worrying..

first thing is welcome to the club. seems like as much you are thinking about it, its going to make you anxious and it will start racing. a vicious cycle. the advice i always give to others and myself is if the dr say your heart is fine, then your heart is fine. my cardiologist just told me recently that you would have to suffer years (like 10+) of palpitations before it really starts to do anything to your heart. hope you get better soon.
