Was PTing at 146....a year later, still at 146

Hello. So basically, what the title says. I have been studying for over a year now (diagnostic was a 139), and a year ago I was PTing at 146. I completed the 7Sage curriculum, read the Loophole, read both LR and RC Powerscore Bibles, and have once again finished the 7Sage curriculum for the second time. The grand finale after all that... another 146 UNTIMED. I am so incredibly heartbroken. I only actually locked into this exam 3ish months ago after a friend also studying for the LSAT convinced me to finally take it in November to help get over my fear of the exam (I had been signing up and pushing it back/canceling for months). I even had a tutor during this time, and he didn't quite help as much as I had hoped. I was also keeping a wrong-answer journal for a short time, but I was getting so many questions wrong and not fully understanding the reasoning why that I got so irritated and stopped.

My most recent timed PT was a 144. I know at this point I have no choice but to retest-- probably in February. Honestly, I'm not sure if I have it in me to keep studying after November and humiliating myself like this. Honestly, I'm probably half-assing my studying compared to others, but I'm not sure what to do, or if I even want to continue this career. Nothing has stuck, I don't know how to effectively study because I've never had to (not that it's an excuse), I've never been good at exams, and this test is just an accumulation of all these things. I keep being told to stop thinking so negatively and that it's all in my head, but I think anyone with this experience would eventually reach this mentality. I don't necessarily want to switch career paths and give up, but I also don't know how much more I can take. I have the grades, LORs, work experience, and an awesome PS, but the only thing holding me back is just a number. I've had to lower my goal score from a 160, knowing that anything lower obviously wouldn't get me into my top school (GSU). What more can I do?

I apologize for the rant, but I just wanted to keep it real in case others were also struggling like this.
