Summary of normal anxiety

Anxiety can become a problem. Small doses of anxiety in certain situations are useful. However, when your child is worrying much of the time, avoiding fun activities, or refusing to go to school because s/he is scared or worried, anxiety has become a problem.

Think of anxiety like fog, if it covers everything, makes it hard to see, stops you from doing what you usually do, and generally gets in the way, then it has likely become a problem.
