I teach a musical instrument 1-1. I have a student who I’ve taught since she was a small child. I like her very much. She is now 17 and over the summer break lost a very noticeable amount of weight. I phoned her mother and asked if she was OK. She said she was absolutely fine, a healthy weight and not starving herself. Every week I worry about her. Her eyes are sunken, her cheekbones sticking out, and I can see the outline of what lies under the skin in her hands and arms. It’s like she is disappearing. Her breath smells bad. I haven’t said a word to my student but I am so worried about her. Is there anything I can say or do that won’t make things worse?
