This is possibly just my paranoia taking over, but I'm concerned that the way my anxiety affects me, it could possibly affect or injure my heart.

What I mean is a lot of times I'll get mini anxiety attacks where my heart will race and i'll get that fluttery uncomfortable sensation in my stomach. This happens almost every day, even when I take my meds. I'm worried that my heart will give out, or something crazy like that. Sometimes I'll get very minor chest pain, but it's not debilitating or even very bad.

Am I concerned over nothing, or is this something that I should see my doctor about?
