单选题
College students are more stressed out than ever before—at least according to the latest findings of a large, national survey. The study found that the way people tend to conceal their negative emotions while broadcasting their happy ones makes the rest of us feel somehow "less than"—as though all our friends and neighbors have better lives than we do. This phenomenon might tie into why students are feeling less confident about their level of emotional and mental stability. If all the students around you are desperately trying to put on a happy face—and you perceive that face as a true reflection of their inner selves, even as you work to hide your own sadness —well, it's not surprising that so many students might be getting a bit stressed out. Instead, if students were encouraged to feel safe expressing their honest emotions, even about their fears and failures, everyone might feel more connected, happier—and, yes, healthier.
