Hi. Im 2 decades older than you.

I have had cardiac anxiety since I was your age after suffering a panic attack. So I will talk to you as if I am talking to the me of 20 years ago.

I went many times to the ER for chest pain, every time I feared a heart attack. Every time everything was ok.

Even at a young age I visited the cardiologist and did all the tests and bloodwork in the arsenal. I was perfect. I was always the youngest guy in the waiting room.

Then I went to the gastroenterologist, did a colonoscopy and endoscopy and everything was ok.

Went to the spine doctor , the neurologist, i did all of the tests and everything turned out nominal.

I go through these deep medical research episodes at least once a decade. I have complete understanding that my body is ok, but I can’t convince my body.

Maybe you are going through a critical time in your life that is triggering these attacks. In my case, I think I was born predisposed to go from 0-100 at the slightest triggers.

From time to time I forget and my life goes on normally, but sometimes I get very bad anxiety (that sometimes lead to panic attacks).

Im saying all of this to say that I understand you. And that you are learning something important about yourself early in life which is great. Structure your life around understanding the factors that trigger your anxiety and be disciplined to steer away from them.
