[单项选择] Don’’t Let Depression Ruin a Good Thing
Feeling down Got the blues You’’re not alone. Everyone gets sad (yes, everyone you’’ve ever met). Some people have sad feelings just once in a while, and others may have sad feelings pretty often. More than half of teenagers go through a sad period at least once a month and plenty of younger kids do, too.
When you’’re in a sad mood, it may feel like it will last forever, but usually feelings of sadness don’’t last very long — a few hours, or maybe a day or two. A deeper, more intense kind of sadness that lasts a lot longer is called depression.
