A friend of mine (15F) has anorexia, but here’s the catch: she doesn’t know I know. Her mom is very talkative, therefore she told my mom and my mom told me. The truth is, my friend does quite a lot of sport and exercise and she lost a bunch of weight in the past year. I should have known. We are going to meet next month and I am worried she’ll know I know if I am too obvious. I think if she finds out her mom told someone, she might lose trust in her and it will make her ED worse. How should I speak to her? Should I tell her I know?
