Anxiety serves a purpose. It keeps you from running out in front of a car. Anxiety becomes detrimental when it ceases to be an internal warning system. Staying away from downtown for fear of being run over is such a detrimental anxiety. Let anxiety serve to guide you, not control you. If anxiety is on a 0 to 10 scale, you are best to keep the anxiety level in the 4 to 7 range. That is very manageable. When it becomes greater, then you need to do something.
