Chronic Worrying. You constantly worry about your family, health, career, or finances. Your stomach churns, and it seems as if something bad is about to happen, but you can't figure out exactly what the problem is. * Fears and Phobias. You may be afraid of needles, blood, heights, elevators, driving, flying, water, spiders, snakes, dogs, storms, bridges, or getting trapped in closed spaces. * Performance Anxiety. You freeze up whenever you have to take a test, perform in front of other people, or compete in an athletic event.
