Hi since the past 2 months I've been dealing with health anxiety and it all started with a panic attack where I couldn't breathe well (hyperventilation) and visited the doctor and there was nothing wrong with my lungs but since then there's a mild pain in heart area which comes and goes specially when I'm laying down or after eating and also took EKG and ECG 2 times but there was nothing wrong with my heart too so what could it be? Btw I'm 20 years old, I don't smoke nor drink and I'm really skinny.
