A panic attack in a supermarket grabbed me out of no where. Approaching the checkout stand, I knew I had to get out of there. Fight or flight. What prompted it I am not sure. But leaving my cart and grabbing my keys, I raced to the car. Once there, I sat and focused on the sign on the window of a hair salon and breathed deeply and tried to 'center' myself, as I dug through my purse for medication.
