     A new study of 8,000 young people in the Journal of Health and Social Behavior shows that

although love can make adults live healthily and happily, it is a bad thing for young people. Puppy

love(早恋) may bring stress for young people and can lead to depression(忧郁症). The study shows

that girls become more depressed than boys, and younger girls are the worst of all.

     The possible reason for the connection between love and higher risk of depression for girls is "loss

of self". According to the study, even though boys would say "lose themselves in a romantic

relationship", this "loss of self" is much more likely to lead to depression when it happens to girls. Young

girls who have romantic relationships usually like hiding their feelings and opinions. They won't tell that to

their parents. 

      Dr. Marianm Kaufman, an expert on young people problems, says 15% to 20% young people will

have depression during their growing. Trying romance often causes the depression.

     She advises kids not to jump into romance too early. During growing up, it is important for young

people to build strong friendships and a strong sense of self. She also suggests the parents should

encourage their kids to keep close to their friends, attend more interesting school activities and spend

enough time with family.

     Parents should watch for signs of depression—eating or mood changes—and if they see signs from

their daughter or son, they need to give help. The good news is that the connection between romance

and depression seems to become weak with age. Love will always make us feel young, but only maturity(成熟) gives us a chance to avoid its bad side effects.
