try, by any means, to distract yourself with something you enjoy, may it be a song you love or drawing, reading a book you love, or watching a funny video. but make sure you can distract yourself until you feel safe again.i will say though, when i was in middle school i cried a lot. at some point, i figured out that reading any random text whether it was a sign or a worksheet gave my mind something else to focus on and it helped me calm down. if breathing exercises aren't helping, try distraction exercises.
