I thought of this just today. But for people without anxiety, I found a perfect way to explain how my mind words. 

Have you ever drove a car with cruise control, set the speed at let’s say 70mph on a quiet, straight open road. Then before you know it, there’s turns, twists, other traffic - but your cruise is still doing 70mph and you get that little panic, fluster moment where you have to hit the brake to turn the cruise off. 

For me - anxiety is everything after the flat road, but struggling to find the brake peddle!
