I think it's something everyone who struggles with the physical side of anxiety goes through.

I no longer struggle too much with anxiety, but am still hyperaware of my heartbeat from when it used to scare me. I have learned (through anxiety) how to feel it in almost every situation, all through my body. When I hold hands, it's in my fingers. When I rest at night, it's in my head. When I go upstairs, I feel it "excessively" in my chest. Anytime it goes above, say, 80, which is pretty common as I'm out and about, I can feel it beating throughout me. I even learned to see it in my vision.

No high blood pressure, or sugar issues, or any other noticed problems. Saw a bunch of docs during my hypochondria days. For me it's just a level of awareness. When I don't pay it any mind it goes away.

But yeah, I can remember going to jog or something and wondering if I was about to die. A pumping heart is a good thing
