Reached a point where im Totally paralyzed with an exam tomorrow

My whole life is in shambles. This was supposed to be a month where i reap and harvest all i have planned for this year, but I have been so inconsistent and am destroying my grades. I'm passing, but not well. Family is disappointed, and as the oldest sibling feels like im failing beyond everything.

I want to do better and feel i havent done enough. I keep falling back continuously.

Currently have a test tomorrow, and it's a big anatomy exam. I tried to study, but I would pray, be motivated, talk all day with the Holy Spirit, then "lemme hop on Minecraft for one second" or "lemme get a few TikTok scrolls," then these choices ruin my whole day, and I end up falling again. And the cycle repeats the next day. I know its my own choices, but im at the point where i ask "how do you make the right choice" ive been so submissive to my flesh i cant say no to the smallest temptations, even when i delete and block things, i can sit 30 whole minutes redownloading them.
