10 days left, need help!!

Hi all, I have been preparing for 1 month now, taken the GMAT prep tests 3 times and noticed that with each test my scores are declining, I feel very anxious and am unable to continue, feels like I've hit the wall

Materials used are OG 12th edition, Kaplan and few CAT books to practice quants, I've almost completed 2/3rd of the OG, details of my scores are as below:

First test taken 15 days into my preparation - 540 (Q 36, V 22)
Second test ten days after - 520 (Q 36, V 24)
Third test 2 days ago - 530 (Q 36, V 27)

My quants score seems stagnant, I know I need to improve a lot, aiming for at least 45+ and verbal does not show much improvement. I realise that I'm not able to complete the quants question within time, so end up guessing the last 3 - 4 questions....with verbal I have issues with RC and CR...I know I'm probably too late now but please advice on how should I spend the last few days of my prep, I know for a fact that I need more practice with quants and time keeping for starters, but with these bad scores, I get all worked up and lose confidence. I keep wanting to take the test again and again, but am not prepared to face the result...please help!
