Guilty that i am not doing what im expected to do

So its been 4 months into 2023 and 3 months into the first N level Exam then another 2 months into the first N level paper examinations. Honestly rn i really feel negative and worrying that i feel like i havent done much in the last 4 months.. I feel like i should be expected to study long hours and even during the weekends at this time but im just keep only watching tiktoks and sleep after school days. I am not really addicted to video games but i dont know if i should stop playing them and also stop doing what i like for the sake of studying. What steps should i do to start studying consistently since im having trouble trying to make time for doing what i want and is it too late to study for pfp now?

sorry if this post is negative as i just want to share my thoughts and worries at this moment
