Recent research and clinical psychologists now suggest that some adolescents are engaging in a newer form of self-aggression — digital self-harm. They’re anonymously posting mean and derogatory comments about themselves on social media.

Child psychologist Sheryl Gonzalez-Ziegler, of Denver, Colo., says it’s a growing problem among teens she counsels. One recent client, an adolescent girl, told Gonzalez-Ziegler she anonymously cyberbullied herself because, as a gay teen, she felt vulnerable and exposed.

“She set up ghost accounts on Instagram and posted mean comments about herself, saying things like, ‘I think you’re creepy and gay,’ and ‘Don’t sit next to me again,’ ” Ziegler says.
