I had a massive fight with my mum. I do dance and this week, is a very important week because Im competing against top 8 dance studios. One of the members in my group is not going to be here and I had to replace her. I've only got 4 days. I have no idea how to dance to it but the thing is, I try to practice. My teacher told me that she's sorry and that she relies on me.I started to get stressed because this is new to me and I only have 4 days left.I told my mum about this and she told me to stop acting so selfish. We kept on arguing about things that don't need to be argued about. She keeps on telling me how useless i am and that im a rude and selfish daughter. I agree but idk how to change. Someone, please help me.

Dear unknown, my mom does have these arguments with me and she does it everyday. Try to makeup with her and act as if you're the wrong one.
All mom's are like that lol
