16-Year-Old Teen With Half A Face Stands Up To Her Bullies!

"Sarah Atwell always listened to her beloved grandmother, who taught her to love herself.

"My nanny always told us when we were sad to cheer us up, 'Be strong, no matter what happens,'" the 18-year-old told ABCNews.com.

But for Atwell, who lives with her family in Nova Scotia, that was a tough order. She was born with neurofibromatosis, which caused a massive tumor to grow on the side of her face.

Now, the story of her psychological and physical transformation, "The Girl With Half a Face," will air on Discovery Fit & Health on Dec. 18 at 10 p.m. (ET/PT), chronicling the weeks leading up to her successful surgery to remove the tumor." - ABC
