How can I get my mom to stop telling me to put on a happy face and get her

[L.H]

to leave me alone? Excuse me for using such language, but I am just so damn pissed at my mom! I am going through some really tough issues and Im just miserable. Ive tried hiding it, but its hard because I cant really act happy if I feel like crying. And because I cant hide it I try to stay away from my parents so then I will never have to deal with their bullshit, but because Im only 13 I still live with them and they just don't leave me alone. I get home from school and go straight to my room and go to sleep, but then when my mom gets home she wakes me up and then asks me "So how was your day? Well, my day was awful because my boss was an ***." and she starts togo on and on and on and I pretend to listen but then when she starts talking to me I give her short answers so then she will leave me alone. And she gets mad so she starts yelling at me in portuguese and she starts telling me "Stop being such an *** and put on a happy face and she goes on and on and on." bot then I just start crying and then she finally goes away. And then I have to deal with her at dinner too because she keeps telling me to eat at the ******* dinner table so I have to sit their and listen to all her crap. She keeps telling me to act like a "normal kid"and be happy or whatever. I don't even like being around her. How can I get her to stop being such a ***** and leave me the hell alone?
