My brother is entering high school in a fairly competitive Asian country where grades matter quite a lot. He has to study for entrance exams and pass quite a lot of tests. I know he has been under a lot of pressure from my parents to do well, especially my dad. I’m currently back from university for the summer. I have seen how my dad lectures my brother for hours and criticise him, filling him with hate and negativity. My brother and I are very close and I have tried to comfort him and we bonded through our mutual dislike of our dad. Recently, I’ve noticed that he has a lot of scars on himself and I caught him poking and scraping himself with a nail a few times. I’ve confided in a close friend because I didn’t want to jump to conclusion and make a big deal, but I’m really worried about my brother. I understand his pressure and from a logical point, it is definitely unfair how my dad is treating him. But I also cannot talk to my dad about any of this because he’s a person that is prone to violence and verbal abuse and when he drinks (which is all the time, usually at night) he’s even scarier by psychologically fucking you up. If anyone can give me some courage or anything, I don’t really know what to do. Thanks.
TLDR; bro is under a lot of pressure from dad and might be hurting himself and I don’t know what to do
