Unable to get over TEAS test anxiety

Hello all,
I've been waiting 2 1/2yrs in a lottery to be accepted to a 2yr RN program in CA. As of a year ago I was informed I needed to take and pass a "TEAS" exam once i was accepted. I was finally excepted in September and have studied ever day since. I have the ATI study manual and have taken the online practice test (w/ decent results 96% overall). My 1st test was on Nov. 27th and I had to leave w/ a massive panic attack right before we were to sign in. It was everything I could do not to vomit in front of the rest of the students. Needless to say, I get really bad test anxiety, to the point where my mind freezes and I can't think. I have one more chance to take it: Nov 3rd (2days away) or I forfeit my place in the lottery and have to reapply. I know the material very well and I have a 4.0 GPA. Every time I think about this "TEAS" test, I work myself up into a state of high anxiety. I tried asking my school if I can have special accommodations, like an untimed and/or taking it privately. They told me because I have never used these types of services in the past, it was unlikely they would grant them now. I have tried simulating testing conditions and do well, but when I tried to take the real thing, I Lost it before i even logged in. Idk what to do. Prescribed sedatives for test anxiety impair my cognition. Man, i've worked so hard for this and I think i've placed so much importance on nursing school that I panic even more than normal timed/ long tests. I have a perfect GPA. Why should I have to prove myself again? This seems like such BS, but these institutions make the rules and apparently, they are subject to change. Any advice would be greatly appreciated.
