My ds, who is the world's best teenager, told me the other day that he & his friends are all concerned about another friend who he says is not eating. They've noticed she's not eating lunch while they eat, she admits she isn't eating, & she's losing weight. (Is not DS pretending to be concerned about friend when actually himself as he eats like a horse and is a healthy weight).
He says they can't approach the parents as "they think she's perfect" (his group of friends are all high-achieving intellectual types). They won't approach the school as apparently (probably due to mandatory reporting) the kids feel they have zero confidentiality when trying to get help.
We're not in the UK, so can't use specifically UK resources, but am wondering in a general way what to say. I'm really proud of him that he's concerned for his friend & pleased he doesn't think I'm a completely useless adult. I wasn't sure what to say, though, & said I'd have to think about it & get back to him.
