HIGHSCHOOL 😫

I'm gonna be a freshman at Pathways Middle College so pretty much my sophomore year I'll take my ACT and if I pass it i can take college courses and graduate with my associates degree as well as my diploma...and I'm scared bc it's a big opportunity and I don't wanna mess that up and school hasn't been started yet and I'm already stressing bc I still want to do sports and have good grades and a great GPA and still have time for friends and also I have this party coming up it's my Quinceañera (Sweet 15) and I still have to plan for that!!! I'm just worried that I'm gonna overwhelm myself..any advice for a freshman??
