Drunk mom

Girlssss I’m a senior in high school it’s just my mom and I. She has always had a drinking problem but recently it’s become extremely worse. She has been drunk for a week straight and I honestly can’t deal w it anymore. Nobody knows about besides me and her best friend I just want her to know that I can’t deal with her drinking anymore, but every time I bring it up she gets pissed. I don’t know how much more I can handle
