why do I get so lazy when moving up is rlly near =⁠_⁠=

I haven't started on any of my lectures and activities:'( neither have i reviewd for our upcoming long test. i don't think I'm gonna be able to get with high honors this year. I haven't passed not one requirements this quarter. Just hope my previous average help my gen. average:')...ik i said i won't procrastinate anymore but every year this happens to me:3 ill be super productive the first part of s.y then id be lazy (too lazy to even get up from my bed and go to school) and literally not do anything. ik i can't keep on doing like this but i rlly can't help it :'(. maybe I'm just not good enough to even call myself an academic achiever? idk. i prlly don't care abt it now anw. I'm just worried with what my parents and friends (or teachers) would think. they already have big expectations from me and I'm wasting some big time opportunities with my attitude. i don't even like being this way tho, i never asked to be perceived as "good" (idk the right word for it) but ever since it started, i ust can't help it. i mean i tried but it always ends up the same outcome. and I'm sure it's not because I'm lacking motivation or I'm just not pressured enough. IM HIGHLY MOTIVATED AND PRESSURED BY MY FUTURE. speaking of my future, i don't even know what to do with that. at 4th grade i alrdy had a concrete plan on what i wanted it to be, then I tried to end it all and now i don't know what to do. should i follow the plan younger me created? or should i follow something new because life isn't the same as it was back then?.
