Im a 22 y/o male, and i have anxiety disorder, i get anxiety when i do just about anything and im tired of it, i get bad anxiety when exercising, when eating, when i get angry, even when i just go for a normal simple walk in the park, i have to admit though that i am afraid of having heart problems, i constantly fear that i will get a heart attack, i always assure myself and know that i dont have heart problems i dont have any history of heart problems in the family, but for some reason its a fear of mine, i also fear dehydrating, i dehydrated earlier this year while running and after that everytime i try to run or exercise or even walk i start getting bad anxiety and feel like im going to faint, also when i eat food for some reason i get bad anxiety, and i know its bc im afraid of getting a heart attack, idk if i am traumatized bc a person i know had a heart attack while eating. Idk what is going on but im afraid of feeling like this, i just want to know if im the only person that goes through this, or if something is wrong with my health, the doctor has told me several times that im okay, and all my lab tests come back good. Idk whats wrong with me. I always fear im gonna pass out or something worse.
