, jealousy can lead to serious problems if left unchecked. The American Psychiatric Association reports that teens who report being jealous frequently are also more likely to struggle with feelings of loneliness and, ultimately, resort to violence. Teens who are chronically jealous commonly have a deflated sense of self-worth and do not feel they are valuable contributors to society. As such, they are more likely to withdraw from peers and, ultimately, more likely to act violently toward their peers.
