Hi,
I've just popped on to reply. Our experience was very similar. DD was top set, but started having problems in school from the end of y9. She was predicted all good grade GCSEs
By y10 she was school refusing, we had multiple agencies involved, as you say the easiest option was to blame my parenting so I had to do parenting courses. We were on the waiting list for cahms having been through pcahms and assessed as needing additional help.
It was then that her secondary school piled the pressure on and demanded an increased from under 25% attendance to 95 in 4wks, with zero additional support. My feeling is that they saw she would be diagnosed with something and I felt she was managed out of mainstream education. As a result I had to dereg to homeschool as they were completely unreasonable and I had to give up work to facilitate.
She then started at a college unit for children who had struggled in mainstream and it was brilliant. Her attendance wasn't amazing but it was better and they were supportive.
She was diagnosed with anxiety and depression at 16 and given medication which made life so so much better for her. She was also diagnosed at 17 with ASD. Again far too late and meaningless as I was given a link to a website and parenting group and basically get on with it.
But the positives. Now she is out of education, despite only having 3 GCSE she has got every job she's gone for and at 20 works in a very fulfilling role and I'm incredibly proud of her.
But I am still angry at school, at the delays in the Camhs system, at the lack of support even with a diagnosis. That the LA was happy for me to dereg without any plan (not their problem!) The pressure they put on her and our relationship, on our family as a whole was immense. Cahms were brilliant when we finally got there but it was a year in the waiting. Maybe if they had intervened earlier, who knows.
It's just so wrong.
