Why is my family so crazy? how to stay busy?

my family is so annoying. i go to work everyday from about 8 till about 1. im 16 years old. i do good in school and sports. im a good person. the only thing my mom does is yell. she yells at the dog, she yells to wake up me and my twin brother and she yells for everything else. because im a girl she expects me to clean all the time. i keep the house super clean. i clean it from top to bottom every sunday. but shell expect me to dust it again on monday. she can never accept when shes wrong and she treats me like im 4. i dont understand. im a mature person. i cant wait to move out. im going to be in 11th grade and i dont know why she acts like this. what can i do to keep myself busy until i graduate?
