How to deal with a drunk mother?

I need help, I just don’t know what to do anymore with my mom. If your just going to have a wise ass comment don’t even bother helping me.. I’m not in the mood to deal with anyone being rude. My moms pretty close to being a alcoholic, she drinks every single day when she gets home from work -gets drunk, picks fights with me and my sister, goes to bed. Every time my mom drinks she finds a new problem that she can yell at us for. She tells her boyfriend and he just agrees that what she does is right. I try to talk to my friends but none of my friends go threw what I go through, I can’t relate to anyone. I talk to my older brother who just tells me to stay in my room. But I’m sick of staying in my room and getting yelled at. She threw her car keys at me like a hour ago for laughing, the car keys just missed my face and hit the window which is now cracked. Her boyfriend said he wished they hit me. Please help, what can I do? I just don’t know anymore
