There is a famous expression in English “Stop the world, I want to get off!” This expression refers to a feeling

Emotions are also easily affected by stress. People suffering from stress often feel anxious. They may have panic attacks. They may feel tired all the time. When people are under stress, they often overreact to little problems. For example, a normally gentle parent under a lot of stress at work may yell(叫喊) at a child for dropping a glass of juice. Stress can make people angry, moody, or nervous.
Long-term stress can lead to a variety of serious mental illnesses. Depression, an extreme feeling of sadness and hopelessness, can be the result of continued and increasing stress. Alcoholism and other addictions often develop as a result of overuse of alcohol or drugs to try to relieve(缓解) stress. Eating disorders, such as anorexia(厌食症), are sometimes caused by stress and are often made worse by stress. If stress is allowed to continue, then one’s mental health is put at risk.
