OK so dd13 is my first born so all this teenager thing is new to me. She is very bright attends grammar school. A few months back she went very quiet. Then started her period so I know there's a lot of changes physically. She seems to have a good peer group but I know there were some changes within the friendship group recently. I thought its all normal girl stuff. We've always let her have her phone (not smart phone) and laptop in her room . She started putting the screen down as soon as we would come in and put a pin on her phone. Her sisters aged 10 and 9 told me they saw some messages to her friend on her phone saying how she hated her life and parents. This is so out of character for her. We've always had a very good relationship where she's been given a lot of love which she always reciprocated. I had a chat with her to ask where this is coming from but she didn't open up. I know she's got into music recently and likes watching YouTube shorts but I can't see anything too concerning on her lap top. However We've now taken the lap top downstairs as we were not seeing her for more than 20.minutes a day in the easter holidays as she was always in her room. I'm worried she may be depressed? She has no empathy at all any more never apologises or comes for hugs etc like she used to. She swears a lot as well at school with peers as sometimes will say the words at home and I know its from school. I feel like I've lost my daughter...am i being ott?? How do I keep.my close relationship with her without pushing her away?
