I'm a 15 year old female in a 4 membered family. My dad is very touchy and verbally abusive towards me and my mom. My brother recently got low marks in his 12th and my dad got really mad. He's been constantly insulting me how I'm gonna follow his path and get low marks as well, he's been swearing at me. I feel at fault because I'm not much of a topper, I do good in school, it's just math in which I fave problems. I feel that if I get low marks my mom will be accused of not raising me well by my dad and she'll hate me. I'm trying to study well but even when I am, he'll come up and say that I'm copying from the internet as I usually keep a phone near me since all my questions are on there. What should I do? Is it my fault? If so, what can I do to improve?
