Karolina and Kaia quickly became friends after meeting at Tree of Life, a facility in Poland for young women battling eating disorders.
Agata, 17, has suffered from anorexia for the last two years. "It all started in biology where we were taught about healthy food and calories," she told photographer Marie Hald. "I liked the control I felt after losing my first three kilos. I felt isolated and had trouble talking about my feelings. For some reason, I thought losing weight would help me make new friends. And then it slowly started: I liked the feeling of hunger -- it made me feel so strong. Never before had I lied to my parents, but quickly I was involved with a whole cavalcade of lies and stories."
Ania shares a room at the facility with two other girls. "I actually had no idea that they Photoshopped the models in magazines -- or that people from Hollywood often had had plastic surgery," she said.
Breakfast is the only meal where the girls at the facility can choose what they eat. Here, Kaia decides which toppings to put on her yogurt.
Agata and Wiktoria play guitar while Ania sings. All three are big fans of singer Demi Lovato, who suffered from an eating disorder herself. When Ania feels sad, singing or listening to Lovato's music helps her.
The breaks between meals and therapy are often spent on blankets on the grass.
Karolina lays her head on the table while other girls read or solve crossword puzzles.
Agata rests on the grass after breakfast. She is anxious about getting well and tries to focus on her goals in life. She wants to become a photographer and see Adele in concert.
"Inside of me is a shadow side. I call her Ana," said Kaia, who imagines a voice in her head that is anorexia.
Karolina and Kaia sneak into the same bed and read magazines together one night.
Karolina sits with her teddy bear before dinner time. Using cell phones is only allowed for two hours a week, and she misses her boyfriend and her parents.
Kaia and Natalia hug on their last day together at the facility. Kaia felt nervous about leaving. She was worried about a life without daily scheduled meals and therapy.
