Last term DD, 12, made a friend at school who self harmed and posted a lot about self harming on social media. I got a message sent to her mother (who i don't know), reported it to the school and had lots of chats with DD about not getting too involved with the girl. DD backed off the friendship and that was that. This term the friendship has rekindled as DD said that the friend is no longer self harming and had improved her behaviour at school. However, this week DD says that the girl is self harming again and a quick check of DDs social media shows that the girl is talking about killing herself. All her messages to DD are odd and I think overly sexualised for a 12 year old - asking DD to kiss her at school tomorrow as a 'joke', saying that someone on FB asked her to give him a blowjob. What shall I do about it? Obviously this girl needs help but I don't want my DD to be involved in what I think is an friendship with weird boundaries. I wonder if she's been abusdx? Am I overreacting? I will tell the school about the self harming and the suicide claims but how do I keep DD away from her? Is it possible? Am I being over controlling? Thanks for any advice! x
