If I had the chance to talk to a teenager who hates her body, I would say, “I understand that feeling. It’s a terrible one, isn’t it?” and then I would ask her about what makes her joyful and what she is afraid of. Eating disorders are mental illnesses that need to be taken seriously and treated by professionals. But for those people who still only coping with confusion about their body image, it is very helpful to have people who will listen to the things they are struggling with.
