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.    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.     They won't tell that to their parents.

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.
