Does your child have trouble coping with stress? Does he or she exhibit serious concern about academic, athletic, or social competence? Do you see an exceptional need for reassurance, frequent aches and pains, acute sensitivity to the comments of others, fatigue, difficulty concentrating, irritability, or sleep disturbance? Does your child quickly give up attempts at self-control or fail to recognize his or her success at such attempts? These are some of the signs of excessive anxiety, a debilitating condition that afflicts millions of children, causing deep frustration and often leading to lifelong unhealthy patterns of behavior.
