It literally happened about 10 minutes a go...after drinking some water I got this weird, strong fluttery feeling in my chest, not painful, just taking my breath away and sent me in panic mode. I just got up out my chair and ran for air. After taking deep breaths I've calmed down and my heart rate has calmed down too.

Ive NEVER experienced this before. Im 19, in good shape-ish bmi is bang on middle...I eat and drink well, got plenty of sleep last night.

Ive suffered from undiagnosed anxiety in the past, at a young age so didn't understand what it was, just thought I was going insane...which lead to some depression. That was many years ago, Ive been fine and happy for about 5+ years now....a bit freaked out by this, was drinking the water anything to do with this??
