So I'm going to the doctors to basically get everything that I'm worried about off of my chest. Lately my main worry has been my heart racing during anxiety attacks and constant palpitations that I've had for years. My main worry is that even after I've been that I won't believe what the Dr says and what more and more tests. This is a never ending spiral that I don't want to fall into. Can anyone please help ? Even if the Dr does the basic tests and tells me I'm ok I really want that to be the end of my paranoia over my heart health.
