Got a bestie you’ve known since college? You could still be reaping the benefits. A 10-year study that followed 169 teenagers from the time they were 15 found those who ranked their close friends as top of the list of peers they’d like to spend time with tended to have lower anxiety, a higher sense of self-worth and fewer symptoms of depression by the age of 25. Researchers say this may be because close, positive relationships with friends boost self-worth and self-esteem at a
time crucial for identity formation.
