Glad to have ya back!! :D
I've been in the same boat about being a freshmen (I'm a junior), and all I have to say is...
Good luck!! (^∇^)ノ
I know how hard highschool can be, I just want you to know that you're not alone!!
I do wish you the best of luck and wish positive things during your year!! (◍•ᴗ•◍)
