I'm starting high school soon

i'm starting high school soon and im kinda freaking out ngl

i signed up for the weight training class and the creative writing class as my electives so i can stay healthy and have good hobbies, but im worried abt weight training bc i dont want to be the only beginner there, or not know as much abt it as everyone else. and i dont really have friends either. i mean, i do have them, but they have main friends so i dont rlly hang out with them unless they ask

I bought cute school supplies in hopes of making school a bit more fun, but idk if its gonna work, and the contrast of my aesthetics might clash too.

anyways does anyone have advice? and not just the "talk to people!" and "focus on grades!" stuff bc it doesnt work for me
