Please, I need some good guidance..

<p>Dear all,
Thank you very much for your time.
I am posting all my stats and hoping that you would give me some good and valuable advises.
First of all, I am an international applicant. I have completed A levels:
Results:
Physics A
Chemistry A
Biology A
Mathematics A
in O levels, I have got 5 A* 3 A and 1 B.
I have been recently diagnosed with GAD and and is a REALLY REALLY bad test taker. My friends are mind blowing.
I took SAT twice and scored this:
1st time: CR 470 M 670 W 600
2nd time: CR 540 M 650 W 570
I tried to give the SAt subject test and b4 the night of the test, I had NO Sleep in my eyes.
These are my scores
Chemistry 740
Biology M 730
Maths II 690
:'(, i scored soo much more in the official practice test...740 in Maths, 650 in W
I thought I did better but ended up with lower scores the last time.
My teachers are really supportive. Although they dnt know i have GAD but they really like me and have given very good recommendation letters.
I want to study meds and from my own personal experience pursue psychiatry.
Its just my SATs are really killing me.....
My top choice in Weill Cornell Medical College in Qatar.
Oh gawd the feeling of dread 24/7 is stressful anf disturbing. And after trying soo hard in the SAT i just ended up with lower scores. I can't even cry so baad.
Please I need your advice. i am planning to write on my struggles and how I am trying to score high. But I am speechless.
The last frigging test i wil have to sit for is IELTS.
If you need more information I am there to give but please do help</p>
