There's a strange new body trend out there that's apparently become the latest obsession among teenage girls. It's called "thigh gap." If you're still not familiar with this term, it refers to the clear space between two skinny thighs that don't touch. ABC's Juju Chang sat down with four junior high school girls about the latest trend that teens are now considering "the ideal body shape." How scary is that?

It turns out that all this blame we've placed on the media telling girls they need to be thinner is wrong. In fact, new research says we should be looking at our daughters friends because they may be influencing these body image problems.

These findings were discovered after 237 girls ages 10 through 17 were surveyed regarding their favorite TV shows, rating how they felt about their bodies, peer competition, and social media activity. They were asked the same questions 6 months later concluding that peer influence affected their self esteem a whole lot more than any celebrities they were exposed to.

Brace yourself because this story will break your heart. When Abigail Lightbown was 9 years old, her parents got worried because she was losing a lot of weight and getting sick every morning. Their doctor said she was suffering from stomach problems, prescribed some acid reflux medication, and sent her home. But the problems continued and her parents started suspecting that Abigail might be suffering from an eating disorder. "I know how some girls are these days seeing all the celebrities in magazines and on TV," Abigail's mother, Bernie, told the Daily Mail. Sadly, Abigail had a much bigger problem than wanting to look thin. She had a brain tumor.

As soon as she was diagnosed, she got operated to remove 95 percent of the cancerous tumor and started intensive radiotherapy and chemotherapy for almost a year. But the cancer returned and this time it was deemed inoperable.
