I need advice

So basically I’m an Irish dancer and recently it’s been getting harder, more corrections, more exercises. There’s also a trainee teacher, let’s call her Emily. Emily isn’t even correcting me, she’s just insulting my dancing. The other day she did it again and I just snapped, I sobbed my eyes out until I couldn’t breathe. I tried confronting her when I calmed down a bit. Then the school owner came over and asked what was happening. I tried explaining but I was struggling to breathe and I only got a bit of the story out. All he said “Emily’s not like that.” Then my mums bf brought me home and I told him what happened. He was pissed and so was my mum. I’m trying to decide whether I should quit dancing or take a break. I know quitting seems like a lot but it’s been burning me out a lot. I like basketball so if I quit I might do that but I’m not sure if quit or break.
