Who suffers from panic attacks here? They are horrible as I had my first one last November and I thought i was going to die, as my head had tension pain and my heart was beating very quickly. What worries me is the physical symptoms, is it too much adrenaline going into the bloodstream or not taking any anti aniexty meds? I've always enjoyed caffeine all my life, but if i touch it know i feel very strange. I've always been an anxious person but never had the weird physical symptoms until i turned 21, what could be the underlying issue?
