why is being this way to me

ok here it is. first my mom never hits me. me and my bother got into a fight at mcdonalds we threw ketchup on each other.im older im 15 he is 13. i got some ketchup on some woman clothes and my mom had to reinburst 45 dollars for the damage. my mom freak out on me told me i was a immature baby and my brother to in front of people in mcdonlads. Leaving mcdonalds she told us that she should get us some pacifers and some pampers and a playpen. people were looking at me. like she was right. she took away my x box and games and i pod i cant go out on weekends now. on the car ride home she is yelling at us telling us when she goes to wallmart she should buy us a cribs and rattles Can i turn her into CPS for abuse saying those things to me? isnt it slander or something saying lies about someone. saying i need pampers and making me look bad in public. just to scare her and For the record he started it my brother not me. its not fair now she is not going to let me take drivers ed in school. she told me that im to imature to drive that babies dont get to do grown up things. she saying all these mean things to me. I have a right to drive? cant they make her a better mom or something. this suxs so bad wut she did to me.
