Like everyone else here I find this heartbreaking. But possibly not so uncommon. I see many parents around me who go absolutely overboard with young children, take them to all sorts of afterschool activities, fuss about their diet and their clothes, change schools and then, when the children reach their teenage and want to start breaking away on their own, they cannot cope with their new independence. Some relatives confided in me some years ago that they really did not like their son! I don´t live in the UK so don´t know about social services, around here, they certainly wouldn´t follow up on a child that was fed and clothed and the only problem was that the parents shouted occasionally. My suggestion would be that you get him to spend time with you, during holidays if you live too far away, his parents may be grateful to have a break and it may help to bring things into perspective. I send you my sincerest wishes that this situation may resolve itself and no-one gets hurt. Btw. the relatives who did not like their son somehow carried on and he is now a fine young man with a family of his own and very close to his parents, who are immensely proud of him.
