     Anxiety is a real emotional (情绪的) disturbance. From time to time, everyone worries about his or her

health, family, money, and school. However, when a person has anxiety, they worry all the time, even when

nothing is wrong. Physical symptoms (症状) can also happen. They may have trouble falling asleep, think

about a particular situation for a long time and find it difficult to think of something else. Sometimes they may

feel restless and sweaty, and have trouble concentrating. They may overeat or lose their appetite. They may

also have a feeling that something bad is going to happen.

     In fact, anxiety is extremely common; it is estimated that about 13% of the United States' population has

anxiety. A study shows anxiety affects all ages, including teenagers and children.

     Many teenagers have anxiety and feelings of great stress, worry, fear and panic. Anxiety can affect many

aspects of a teenager's life. If a teenager is always anxious and worried, it might affect their ability to make

friends, perform well in school, and try new things. It is doubtful whether he or she can fully enjoy life. So

the most important thing is to understand that anxiety can be treated and to help them have a happy and healthy

life.
