Existential crisis anyone??

ngl as it's getting closer to the end of the GCSE season im starting to feel like 'what's the point of this'. I know my tone may feel sombre but it's scaring me how quick the past 5 years have gone. If 5 years felt like that then now ik why so many people say '' life is too short'' and i keep getting bombarded with thoughts of how i will look back at these days when i am older and say gosh this feels like yesterday. Idk if it's cos of GCSEs that im having these thoughts but i just feel so down and feel like what am i going to do after these exams. Like yh ik it will be relaxing having a lie inn but that's it. Next will be 2 years of A-level then 3-6 years at uni then a job for my whole life then retirement then death crawling at me( if i live that far)---Lol reading over this i sound like im signing my death warrant tomorrow. Do you feel the same???
