I get angry so easily.. please help.?

My mum know's I get wound of very easily. I've told her so many times. But she still winds me up. She lies to me. All the time. About thing's she's said and done. She act's like a child. She pretends she hasn't done things and said things to me that she has. Today, she had her phone turned off. I called the home phone her mobile, everything. I even called her friend at work but she wasn't there. I was away with friends and had to be taken back home by someones da who was already running late somewhere. I got home she then blamed it on me for not organising myself, she thought my dad was taking me home, but he had to go out at the last minute and I couldn't get hold of her on the phone. I got home turned out she was at the park with my sister. She could of sent me a text saying so. I called her 13 times on her mobile 7 on the homephone and twice and work, and she's blaming it all on me. Sometimes when I cry, she says " yeah that's it act like your lifes crap." it's not. I just cry because of her. She has no idea how I feel. I want my dad back. I need him. but thats past now. and she doesn't seem to understand that. And don't dare ask me to talk to her about it, because she'll just say I'm pathetic, and that I'm talking crap.
