i'm homeschooled so take this with a grain of salt, but i would bring some headphones and during lunch or a bathroom break and play ur favorite song. Also drawing literally anything can help. doesn't need 2 be good or even like an actual drawing, jus random shapes and lines or whatever u can think of. also Dont forget to breath!! breathing is such a huge part of calmin down, so just try to focus on how ur breathing. hope this helped a little ????

@Cl0wnp0p_mp4 thank you for the advice ill try it out before music class!
