Why do you want to quit pointe? How long have you been doing ballet, and how long have you been doing ballet en pointe? How old are you?
You can talk to your mom, and ask her why she seems to want you to continue doing pointe. If you disagree with her, you can respectfully and calmly tell her the reasons you want to stop doing pointe and see whether or not your mom will let you do so.
While I know there are ballet teachers who sometimes put students en pointe sooner, if you have had less than 3 years of at least 3 ballet classes a week, you could tell your mom that you think it is questionable that you should even be en pointe. If you have at least that amount of training in ballet, and think you lack the strength or technique to be en pointe, you can tell your mom that. Youths' bone maturation differ, but if you are younger than about 11-13/14 years old (and if you are under 13 you should not have a Yahoo Answers account) you can tell your mom that you may possibly be too young for pointe shoes.
