TYLER - A group of doctors in the online journal "Pediatrics", say Facebook, the social networking site, can be especially tough for individuals dealing with poor self-esteem.

The group claims Facebook's "friends" tallies, constant status updates, and pictures of happy-looking people having a good time, can make some students feel depressed.

The researchers also adds Facebook depression to a laundry list of potential harms linked to social media such as cyber bullying, and sexting.
