In winter，when the sun hides behind the clouds，everyone feels a bit low. You may be tired and find you want to sleep all the time. What you may not know is：you are suffering from (患有) SAD(季节性抑郁症)．

But don't worry—it's normal. Colder temperatures and fewer hours of daylight can steal your energy and put you in a bad mood.

Read on to find out what SAD is and what you can do to help yourself or those around you.

These days，Linda，a US teenager spends most of her holidays sleeping instead of doing sports outside. She has also had trouble concentrating(集中精力) on her homework. When her mother asks her what's wrong，Linda doesn't know what to tell her. Linda may not realize it yet，but she's suffering from SAD. It causes people to sleep，eat sweet food and get sad or angry for no reason.

About 15 percent of American people now suffer from SAD in winter according to the US Department of Health. The US government has taken measures to help people beat it. Local communities encourage people to take part in activities such as exercise，dance or art. And they advise people not to eat too much sweet food.

Like in the US，cold northern European countries such as Finland，Iceland and Russia see a large number of people suffer from SAD every year. So，the sunlamp is widely used in these countries. It's an electric lamp which is just like a “little sun” that gives off light to make people think the sun is shining and feel better.

Linda Evans was my best friend—like the sister I never had. We did everything together: piano lessons, movies, swimming, horseback riding.

When I was 13, my family moved away. Linda and I kept in touch through letters, and we saw each other on special time—like my wedding (婚礼) and Linda’s. Soon we were busy with children and moving to new homes, and we wrote less often. One day a card that I sent came back, stamped “Address (地址) Unknown. ” I had no idea how to find Linda.

Over the years, I missed Linda very much. I wanted to share (分享) happiness of my children and then grandchildren. And I needed to share my sadness when my brother and then mother died. There was an empty place in my heart that only a friend like Linda could fill.

One day I was reading a newspaper when I noticed a photo of a young woman who looked very much like Linda and whose last name was Wagman — Linda’s married name. “There must be thousands of Wagmans,” I thought, but J still wrote to her.

She called as soon as she got my letter. “Mrs Tobin!” she said excitedly, “Linda Evans Wagman is my mother. ”

Minutes later I heard a voice that I knew very much, even after 40 years, laughed and cried and caught up on each other’s lives. Now the empty place in my heart is filled. And there’s one thing that Linda and I know for sure: We won’t lose each other again!
