My Self-Sabotage

I've always done grand in school like I barely did anything for my junior cert and got all higher merits in choice subjects and merits for English, Irish, and Maths, but I've always just been the biggest procrastinator ever. The leaving cert is in 6 days, and I have genuinely done next to nothing outside of school to prepare. Since like March I've spent hours in my room from after school until like 8 or 9pm "studying," but I legit have watched hundreds of youtube videos instead of doing any work. Like, I know i need to study, and i want to study so i can do well, but my brain just forces me not to. It's weird because I'm so disciplined when it comes to my training and nutrition (I literally track all of my calories down to the gram and I'm yolked not to self glaze) but when it comes to study there is like a mental block I swear. My top cao choices are in the 460-510 range, and i got around 430 in the mocks by winging it (sporadic study in the weeks before, nothing structured). I only have 6 days which is honestly probably less than I spent for the mocks. I'm in higher level everything except Maths. See the thing that is most stressing me out is the fact my parents are so proud of all the work I'm putting in and they are honestly the greatest people like I'm so lucky but I feel like they are going to be so let down if/when I don't get high 400s and I feel so unbearably guilty everytime they ask how study is going and I'm like "yeah grand". One of my backup options is low 400s and I'd honestly be just as happy to do that one as I would to do the top ones on my cao list but I'm terrified of the results day and the reaction if I end up getting low 400s or worse. I know the leaving cert is not the end of the world in the grand scheme of things but for now it feels like my world is falling apart and that ive been kicking this can down the road that has finally reached its end... ive never used this app before so idk what im expecting out of this i guess just want to see if anyone relates. thanks.
