My mom annoys me

I,15, used to live with my grandma but after moving countries I now live with my mom. But she just annoys me so much and I don’t think I can live peacefully or have a good personality around her. She keeps talking to me when I just want to be quiet to myself and she speaks Chinese which I don’t like to speak, so I’m trying to avoid it as much as I can but she just gets pissed. I don’t like her mannerisms of being conservative and it’s gotten to the point where just seeing her puts me in a bad mood. She’s not evil but she just doesn’t know when to not talk. She talks so much about food: it’s always ‘so you want to eat that’ or ‘what do you want to eat?’ And it’s normal but she speaks about it endlessly even when I ask her to just stop. She’d force me to eat stuff I don’t want to, or force a certain amount of food into me because apparently I don’t know if I’m hungry or full. And now I’ve developed an eating disorder because of her annoyance. I associate food with pestering and it’s just gross to me now and I can’t even swallow anything without feeling disgusted, I have to force it down my throat if I want to not starve and I’d gag at that. Her persistent speeches about food definitely does not help. I cannot stand her at all and I don’t know what to do about it now that I live with her. I also don’t like her casual talks or anything that comes out her mouth.
