Is it worth submitting an extenuating circumstances form for Cambridge?

Hi, I'm looking to apply to Cambridge in October to study Linguistics, and wondering whether it's worth me submitting an extenuating circumstances form.

For context, I'm predicted A*AA and my gcses were 98887777776, which unfortunately was rather average for my school.

This is where the potential extenuating circumstances come in to play. At the end of year 12 after struggling for years I was diagnosed with autism spectrum disorder, generalised anxiety disorder and major depression. The late diagnoses meant that I had been receiving no support or accommodations at school, and struggled greatly because of it. I spent most of years 10, 11 and 12 having daily panic attacks, being unable to concentrate in lessons, having to leave classes to calm down, losing sleep (to the point of sleep deprivation) and having relatively regular absences due to being unable to make it into school. To me this significantly affected my education, and contextualises why my gcses were not as strong as they could've been. My year 11 mocks had been much stronger (99998888877), however my anxiety became significantly worse after they took place, and the lack of support led me to missing even more classes and even having panic attacks during actual gcse exams.

I don't know if this counts as enough of an extenuating circumstance, though.

Just to add a little bit more of a dilemma, my school is not known for being overly cooperative. They were the reason that my parents had to pay for a diagnosis, as they refused to refer me due to my grades being fine. I'm worried that they just won't fill it in.

Any help/input would be greatly appreciated!

Are you getting extra accommodations now?Also have you had any therapy to help you learn to adapt to your condition.

I've recently had a support plan put in place with accommodations for both in the classroom and exams (although I'd argue it still needs tweaking because they were not being overly cooperative or even properly acknowledging my needs). Therapy is a work in progress atm, attempted CBT and it did nothing for me, so my psych recommended EMDR, but trying to find and finance that is proving difficult atm so hopefully by the end of the year

I'll also add that it seems to be somewhat useful atm- I've only missed one class so far this year due to a panic attack compared to this point last year when it would've been closer to one a day

My daughter has been having specialist therapy for about 4 months now and it has worked wonders.Costs are a factor I know and we have been through various avenues before this which have not helped including CBT.I am glad things are improving for you now.
Back to the question yes it would count as extenuating circumstances for Cambridge.You would still have to hit your grades this year but it would explain your journey to this point.

Thank you! now just to broach the issue of my school being quite unhelpful... im sure trying to get them to fill it out will be a delight
