what many of you describe might not lead to a diagnosis of ASD especially for girls.
My DD was not diagnosed, but described as 'complex' with ASD traits (although some therapists disagreed she even had traits). . however, any information about the way their particular brain works, is helpful for making their lives easier in education and at home, so I would recommend ed tests like wisc4 and camhs assessments less for diagnosis, than understanding what treatment and support might help.
I found education reports more useful than camhs letters (and my DD was hospitalised for a time) for getting extra support at schools, in exams, and even for the LEA to change college and educational charities to support her.
If you suspect ASD traits, theres a few books re Aspergers girls which have information and advice.

One thing I realised is that the world is pretty stimulating for my DD and she needs more quiet and alone time to cope and thats ok. She had learnt how to behave like us for so many years, so no-one realised how hard it was for her in everyday situations like shopping etc. I thought she was just shy.
I would say its really important to help them learn coping strategies for emotions through therapy, even when its difficult to engage, please stick with it and ask to change therapists if necessary, as my DD does use most of the strategies she has learnt.
I wish CAMHS support for you all had got better rather than worse over the last 4 years...
aphrodite, thank you for your words, especially your last paragraph which reminds us to hang on in there as it does get better . At this age, lots of bright teens are diagnosed with dyslexia and dyspraxia, often revealed by the demands of school work changing. If familes and kids are aware of this, there is help available for the extra stress school puts on you. so glad to hear you are feeling stronger. My DD too, is also doing well and is happy at university. Some days are still tough, but she has like you, learnt coping strategies which really help.
