My DD who is 13 really seems to struggle with friendships and I'm not sure if there's anything I can or should be doing. She was in a group of about 5 friends at primary/middle school which was then separated at secondary school. She started secondary school in the same form as two of them. Since then (she's now in year 9) she has one new friend and that seems to be it. Her friend was on holiday last week and my dd stays she spent every break in the library or locking herself in the toilet. She told me she felt lonely at school and feels she's a loner. She said everyone knows she has no friends. She asked me not to talk to her school but I did as I was so worried about her. Her form teacher said she'd noticed that she was much quieter than she had been in year 8 and would have a chat with her. My dd is now upset that I spoke to the school and is embarrassed that her teacher now knows she only has one friend. A few people have made horrible comments about her lack of friends and the odd nasty comment. I do worry about her. She's one of the youngest in the year and I think feels out of her depth. I would really appreciate some advice.
