DD is 16 and diagnosed as autistic. She has been self-harming now for around five years - cutting her arms and sometimes her legs. She is covered in scars. It got much better but over the summer it has really ramped up again. She has had a succession of private counsellors and therapists but has not found any of them useful - she has just stopped with the most recent one.
She won't tell me what are the triggers for her current self harm (but recently has started leaving out bloody tissue etc., which I take as a sign she wants me to know she's doing it). She identifies as trans and has a trans partner who she spends a lot of time with. I am also concerned she has started restricting food - this happened in the past but resolved. She is out the house a lot so it is more difficult for me to keep tabs on this.
I'm at my wits end. She won't talk to me so I've asked her to consider another therapist. She hates being challenged and approaches like CBT apparently "don't work" for her. She's happy to talk about her feelings with a therapist and is extremely intelligent and articulate, but seems much less able to take real action to change her thought processes or move on. She has told me she is not sure if she wants to stop self harming - I think this (and mental health difficulties more broadly) have become an integral part of her identity. She has a group of friends who are all trans-identifying (and my guess is all autistic although not all are diagnosed) and mental health issues seem to be the norm within this group.
She will be going to University next September and I feel really concerned about her going while still so mentally fragile - transitions are hard for anyone but for someone like her it could be catastrophic, and I'm so worried that I won't be there to spot anything. She won't consider a gap year and doesn't want to live at home. I feel we have a year to try and get her in a better place (while also doing four A levels!). Any advice would be really helpful - types of psychotherapy that might suit her and she might engage with, helplines etc. We don't seem to have any specialist self-harm organisations in our area but am aware of some of the national helplines etc. CAMHS were useless.
Thanks very much.
