Writer Jodi Picoult describes anxiety "like a rocking chair. It gives you something to do, but doesn't get you very far." Ordinary anxiety surfaces when we feel vulnerable, like having butterflies in your belly when doing something important the first time, feeling jittery before speaking in public, or worrying while waiting for important test results. Anxiety prods us to think through decisions that matter. If we rock in that chair too long, we forget how to get up and move. If we get stuck on too many decisions, we might need professional help to move again. Information is widely available about anxiety disorders, but normal anxiety can be helpful.
