I'm terrified of my Heart Attack symptoms, too.
I've gone to the ER so many times with chest pressure, chest pains, numbness, breathlessness, headache, etc.
I've even had my whole left side go suddenly and completely numb/tingly!! Talk about terrified....
has happened to me 3 times....each time resulting in an ER visit and the doctor telling me, "There's nothing wrong with you."
Yeah, someone forgot to tell my body that....
Anxiety sucks....but it is what you have.
Sweetie, you have to truly accept the diagnoses, relax, and try to learn techniques that will help you.
I know that it's all easier said than done...believe me, I truly know...but work on it daily.
