It's a struggle for a lot of teens - wanting to look their best for that next selfie or thinner at the homecoming dance.
Moving to a bigger school and working to fit in, 14 year old Lily Pennington from Charlotte found she was anxious around food, and always wanting to exercise.
"Every month I lost weight," she says.
Reality really set in for the family when Lily got the official anorexia diagnosis in April of 2015.
It's an everyday struggle, but today the Charlotte High School Freshman is on the mend. Now, Lily wants to break the silence that often surrounds eating disorders like anorexia.
"One of the stereotypes is that people think...people are just doing it for attention," says Lily.
Lily isn't alone, 30 million Americans will deal with an eating disorder at some point in their lives, many of them teenagers.
In this social media age, there's a real pressure to look "selfie ready."
Log on to to Facebook or Instagram, for a lot of teens, it's hard to miss those images that glorify a certain body type.
"Social media also seems to have a large impact," says Lily's mom Alisa.
Lily's parents say the key is to really talk as a family. Plus, check up on your kid's social media accounts.
"There's a lot of pro-eating disorder websites out there, and a lot of exercising websites," says Lily's dad Mike Pennington.
It's a journey that has brought the family close, and inspired Lily to help others.
Lily still sees a specialists today for her anorexia.
Lily, her friends and family are walking in the National Eating Disorders Association walk this Sunday in Ann Arbor.
