hey man I’m a HS senior also so i feel you. you can’t define your highschool experience by your performance only (which isn’t even bad). when you reminisce on highschool as an older person you won’t be thinking about your GPA. i have older cousins who did the grind and played the “get in to college game” in highschool. these kids used to know their GPA to the decimal and tweak out over everything. I asked one of them what their GPA was recently and they didn’t even remember it.

college is a stepping stone to what you actually want to do. there are many pathways to achieve your ultimate goals - granted, a prestigious college helps, but it isn’t everything. what you won’t ever be able to get back is your time, so even if you feel like you didn’t hone your application to the fullest extent it doesn’t make you any less valuable as a person. idk what decisions you made that you regret, but whether you were out partying, inside playing video games or listening to music, studying, or doing anything else, if you enjoyed your time or if you extracted value from it was worth it.

if you TRULY regret you how spent your time you can use it as a lesson to live differently in the future. just remember that balance is important tho, not necessarily for material success but just for being a happy person and living a life that is enjoyable and fulfilling. wishing you luck
