Im 16, not overweight, do a little bit of sport here and there. Had a doctor check me out last week listened to my chest and it was fine, BP was fine and full blood count blood test was fine. Im having, what i hope, is a panic attack, my heart cant just stop can it? I mean i know it can, but what are the chances of having a cardiac arrest this second? Im scared and feel like I’m on the brink of non-existence, but I’m just overwhelmed and overreacting aren’t i? I gonna be fine aren’t i? Would be a shame i were to not be fine anyway.
