I understand it frustrates you, but it worries me when kids feel they need to parent their parents. They’re the adults; you’re the child. I believe you should be telling your mother to talk with her friends, her family or even go online.
You should concern yourself with study and friends and developing skills that will help with your future. Your mother is the one who should be focusing on creating a better home environment for you. That’s her responsibility. I don’t want to sound mean, but she needs to be the grown-up, not you. Encourage her to talk with other adults.
