Hi, I'm a 16-year-old male and today I had a very scary incident. I was driving on the freeway and happened to merge and not see someone, and this person decided to take it personally and followed me for a couple miles. Eventually, the person pulled up next to me and flashed a gun. I was very scared and could feel my heart start racing and I began to feel a tingling sensation in my arms and most of my upper body. It became very hard to drive and I eventually came across a state trooper to ask for help. I got out of the car and started feeling dizzy and I could not catch my breath. The trooper told me to breathe and I felt my heart rate starting to drop. I am not sure if this was a panic attack or a Heart attack or what it was, but any help I could get on this would be greatly appreciated.
