I heard my leg snap and my mom rushed into the room.
What were you doing when you heard your leg snap?
I was jump roping to a quick beat.
I think it was nice that your mom came to check on you. It is good to care about your child's health. Your mom cares about you enough to help you and you should be grateful.
I don't need her help, I can do everything by myself.
You should appreciate the fact that your mom checked on you. Even if it doesn't seem like you needed help, it's unlikely that you can deal with a serious injury alone. You should tell your mom you'll accept help.
