It’s not your GC’s job to file for accommodations until you or your parents ask for it. They need to be filed for approximately 8 weeks before the AP tests.
Do you have an IEP? Do you have accommodations for tests at school?
The only possible out you have is if your school would agree to accommodations that do not violate the AP exam rules. If you can’t bring in food or drink, can you have a separate testing area with your own proctor and they can bring in water for you in a cup? No bottled water and no food and drink during testing according to the College Board.
It sounds like you set yourself up for a problem. The other alternative is not to take the tests.
And do you realize that accommodations for the PSAT or SAT would not apply to AP exams anyway? If you do have an IEP, the school needs to get on board.
Any student without an IEP who has significant test-taking issues really needs to take stock. It will be more difficult to get accommodations in college if you don’t have them in high school via an IEP.
It is NOT the school’s job to file for accommodations until you ask for them. As a parent, I did all the research myself for my son who had a 504 plan in high school, and the school filed upon my request, and I helped them when the request was initially rejected, by filing doctor’s paperwork with the College Board.
If your anxiety is truly SEVERE, you will have a doctor who is able to corroborate that, or in essence, you don’t have it. I have issues at work where coworkers say they need this or that accommodation, but when it comes down to it, they don’t have medical backup so it is like they have no accommodation at all.
Good luck, but even with the makeup test dates, you’ll be lucky to get any accommodations.
