Beat by GMAT

Hello everyone, I just took the GMAT today for the third time, and I got a score of 530. I am extremely disappointed. It doesn't make any fxxking sense. The first time I took the GMAT, I got 510. I was not happy because the minimum requirement is 550. I can blame myself that I did not study enough because I only studied less than 10 days. I studied another month before my second attempt, and I got 460. WTF is this? The more I study, the lower I score. My family told me not to give up, and I studied another 2 months. I studied at least 6 days per week, and I did all the questions in the OG 11. Today I got 530. Wow, a huge improvement of 20 points compared to my first attempt. The different of studying for 3 months and 10 days is only 20 points. Why do I wasted my fxxking time of doing the fxxking questions over and over for 20 points? Maybe I am just a loser, no matter how hard I try, I can only get less than 550 in GMAT. I just want 550, did I ask for too much? Should I give up because I don't see any chance. There is zero or negative correlation between study and score. Sorry for releasing negative energy in this forum.
