Thanks for the comments.
We don't have anger or conflict - we have radio silence. She is 14 (just). She has a peer group of 5 friends - one was transgender but is now non-binary, another two are transgender, two of those three are gay, another one has no particular label, another one is a boy. They change these identities and self beliefs so often I can't keep up. DD used to say 'i'm the only 'regular' one'.
She says she has anxiety, she says she has panic attacks - i've never seen any but she says they only happen in school, so we got her help via school from the school therapist. He won't divulge of course, but what he would say was 'i'm not worried about her'. I asked him if I should be considering a referral for ND type disorders or her MH, and he said he could see 'no evidence of that'.
She self harmed last year, but I would say more experimentally (she said her peers talked about it so she wondered if she should). This was, she said, driven by the stress of tests at school. The therapist covered this in sessions.
She accidentally left/dropped a notebook in my car a couple of weeks ago. Shes's a prolific writer so I assumed it was more musings. It was. but at the back were pages of writing about how she isn't wanted, she's still hurting herself, she is stupid, she hates herself, she hates me. She says she wants to be a 'he' like her other friends are. All her peers have huge issues, not just the things above - self harming, eating disorders, you name it. And I honestly feel it's just contagious - shes jumping on the bandwagon. If there isn't a trauma going on, she doesn't fit in. There is so much angst, and so much hyperbole.
She won't talk to me. She doesn't even want to be in the same room as me.
One week she will be asking me to curl her hair and she'll watch a favourite film with me, the next she's not showering, not washing her hair and living in a filthy tip. Then I think it's all normal teen stuff, till I realised she was wearing double bras - presumably to flatten her chest - what's that about? and writing about hurting herself again.
How much of this is real? How much should I worry about? How much is just normal or because her mates do it? Are these peers an issue? why is she so attracted to these types of friends?
I have another DC who is the most biddable, loving, carefree child. I feel like DD is a stranger to me, and I just don't know what to do for the best.
