My mom is such a jerk sometimes what do I do?

She is so mean and rude to me. And she justifies it with the fact that shes the adult and I'm the child. This is becoming a little rarer, but sometimes she even thows things, she'll just get pissed and then she'll like throw a book or something. One time I accidently got super glue on her desk, like one tiny drop and she went totally insane. She started screaming and threw the locket I had been trying to fix on the floor (broke and lost it) and I ran and hid down in the basement. When I came back up she totally *****ed me out and screamed at me for hours. Over a stupid drop of super glue. Sometimes shes so nice and fun and we have a great time together. And she does a lot of good things for me. But then she'll just be a jerk. This is just a minor example, but today I came out and said goodmorning and all and she was watching TV. I told her I had wanted to play this one game. She said that was fine. We watched the news together and chatted and everything was just fine. Then she got up and walked away to go do her paperwork that she had said she was going to do. So I asked "Hey, can I play it now?" and I suppose I should have said please or something because then she was like "UGG, I don't need this pressure right now!!!!!" so I thought ...okay... and went in my room to go back to sleep and she came in and was like "you can play it for a half an hour. Thats it." I guess just to demonstrate her motherly power (which she does quite often be the way) even though she really had no cause to be so stern. Because I had never played the game before or gave her any reason to be upset over it. So anyways, I didn't go out I just tried to go back to sleep. Like I said that was SUPER minor. But its even just little things like that that eventually build up and reallly GET to you. Anyways, I need to know what to do and how to react when she gives me crap. Moving out is not an option, I'm not an adult yet. Normally how I would react is just listen to her tell me how wrong I am and then go in my bedroom and silently cry. Although, sometimes I get sy back, but this does absolutely no good because then she actually has a reason to be mad at me. I really want to know what to do... can anyone help me?
