Yes! I was having a terrible morning worrying to the point where I began to have a panic attack while driving - full blown, palpitations so loud I couldn't hear anything else, extreme tunnel vision, etc. I basically turned to the side of the road, put the car in park and shot straight out of the car towards a ditch worker, crying to him that he needed to call an ambulance because I was that convinced I was dying right then and there. Before he could go and get his cell phone out of his car I whipped my own out and dialed them myself, and he looked very confused. I still feel very sorry about that to this day.
Sure enough, the state trooper came and stayed with me as the ambulance came, as I started to come to my senses. It all led to a very embarrassing time with them as I cried about not wanting to go to the hospital since I realized it was a panic attack and then had to find someone that was available at that time to come and take me because the police refused to let me go home by myself.
Probably one of the most cringe worthy experiences of my life to this date, haha.
