Every child should be checked for anxiety. Anxiety is the mind and body's reaction to stressful triggers. 40 million adults in the U.S. (18%) have an anxiety disorder. 8% of children and teens experience this. Most people develop symptoms before age 21. Most children don't even know what anxiety is. People ask them if they feel anxious at all, but the feelings are never described to them, so they think they never have it. If children start going to the doctor to get checked for it if they have anxiety, they can get medicated for it and save them a lot of issues in the future.
