I feel you. I think it's important to keep in mind that GRE is NOT an objective evaluation of your intelligence. What the GRE evaluates is... well, your ability to take the GRE. It is so specific in its approach that pure intellect is not enough. Your ability to understand what is expected from you is key here.
Now, if you have tried everything and you can't mold your brain to fit into this ridiculously specific test, then that simply means your strengths lie somewhere else. Maybe focus on what you CAN improve: your personal statement, your writing sample aso… ask other people to review your application. I am not sure where you applied? if you only picked top universities, then your otherwise satisfying application might just not be enough in a high competition environment.
I hope you get better soon!
