The Value of Tears
Tears can ruin make-up, bring conversation to a stop, and give you a runny nose. Tears leave you embarrassed and without energy. Still, crying is a fact of life, and your tears are very useful. Even when you’re not crying, they make a film over the eye’s surface.  
When tears fall, they reduce stress. But we tend to fight them for all sorts of reasons. “People worry about showing their emotions（情绪）, afraid that once they lose control they’ll never get it back.”   After we cry, the  feelings that caused the tears often disappear.
Sometimes people become much stressed and can’t cry. Whatever emotion they are feeling — shock, anger, fear, or sadness— is being held back.
But everyone has the need to cry. Psychologist Vera Diamond explains that her treatment often consists of giving people permission to cry.   Patients practice crying just to become used to expressing emotions. She suggests safe, private places to cry, like under the bedcovers or in the car. Crying is a way of ease tension, but people don’t like it when others cry because it makes them tense. And they’ll do just about anything to make you stop.
In certain situations, such as at work, tears are not appropriate. It’s good not to cry during a tense business discussion.  You should also act out the whole situation again and be as noisy and angry as you like. It will help you feel better. “And,” she adds, “Once your tears have taken away the stress, you can begin to think calmly of ways to deal with the problem.”
Tears are a sign of our ability to feel. If you find yourself near someone crying, deal with it. And never be afraid to cry yourself.
