Replying to My mom is ridiculous

She's never been fair with punishments or anything but lately it's gotten out of hand. I got my car taken away yesterday, which I paid for including insurance, gas, repairs, because I said "I already told you" after she asked me for the 5th time if I was skiing today. I didn't say it mean in any way and she flipped out and starting screaming at me saying how snotty I am to her. Well I'm not but I'm not going to do anything nice for her anymore. She yelled at me this morning because I wanted to bake the cookie dough she made. She actually yelled at me because I wanted to help. I accidentally got 1 fucking piece of dog hair on her and she flipped out saying how I ruined it. She had been baking in it and had flour and dough all over it. I mean I know parents arn't always perfect but seriously, this is just retarded.
