SHOULD I TRANSFER HIGHSCHOOLS?

i've been indecisive about which school for 2 years now. i'm in gr9 and will be going into gr10. i'm currently at this school right now, and it's okay. i've got lots of friends, but they get on my nerves a lot LOL. the education is okay too. and in the other school there's this course (dancing) i want, and a program called leadership, it's AP ss and AP gym and i'll be in AP english. in 4 classes you have the same classes with the leadership people, so it's gonna be hard to make friends when they've been together for 2 years. and i barely know anyone at the new school so it's gonna be a lil hard to make friends too. what should i doo? i know i should follow my heart, but i'm COMPLETELY INDECISIVE. help me please!!
