Feeling stranded

Hello. I am a 17 year old student from singapore and i finished my final exams at the end of last year. 2024 was an insanely hard year of me of revising relentlessly and mindlessly to do well for my exams and during this point of my life, all i could dream of was the day where i finished my examinations and i thought that i would feel reborn and free to live to life i want to live, given that i worked extremely hard for my studies and i thought i would finally have some free time for self improvement and hobbies to make myself feel happy. On the day of my last exam, first thing i realised was that for some reason, i didnt feel any extreme form of relief or happiness and i felt as if it was just an ordinary day, just without studying. This cycle continued on and on as i have a shaky part time job and a bunch of free time to do what i want. The thing is, however that i feel like i rlly do not have any goals or aspirations that i want to achieve and always find myself scrolling without an end goal in mind and i always feel like a piece of shit at the end of every day. Any ideas on how to live my life more positively and productively so that i dont feel so negative ab myself
