Actress Brittany Snow says she couldn’t have beat her nine-year battle with anorexia without the support of actress (and best friend) Sophia Bush, reports.

“Sophia gives really, really good advice,” Snow, 22, reveals in the May issue of CosmoGIRL!. “I was going through a difficult time, and she was going through a difficult time ... When somebody can be there through something like that, they’re a friend forever.”

Snow says she decided to make her struggle with anorexia public after two of her friends died from an eating disorder. “I was devastated,” she says. “I have so many girlfriends who are not even in Hollywood who struggle with eating disorders.”
