Seeking Prayers to Overcome Family Stress and Exam Pressure

Assalamu Alaikum, everyone. This might sound like a silly ask with all the details I'm sharing, but please hear me out and try to support me, insha'Allah. I'm currently in the middle of my board exams. I didn't do well in the practice tests earlier, which meant I had to switch schools to take the boards. I have big dreams for higher education and a lot I want to achieve. But for the last three years-honestly, my whole life, but especially these past few years-my family has been really tough on me. No one's telling me to drop out or anything like that. It started with my dad insisting I study a subject I had no interest in. I went along with it and even reshaped my goals around this field. This area needs a ton of focus and long study hours. I gave it my all, I really did, but it's been so hard because of the situation at home. My family has disappointed me so many times over the years. Doing well in these exams feels like my only ticket out of this house. I don't want to cut ties because they've done a lot for me, but I just need to be on my own to focus on my dreams and career without all the distractions. My brother, who's just two years younger, is incredibly disrespectful to everyone, including our parents. I think it's because they've always spoiled him and never taught him any discipline. Now he has no respect for them or for me. I won't go into too much detail, but my parents have lost hope in his future. They see me as their only chance for a better tomorrow. After years of being treated unfairly, they've started to support me a little-but what a cost! My brother doesn't study, he's always glued to screens, and he bosses our parents around. It's all too much. I'm really sorry this is getting long. At home, there's constant yelling, screaming, and things being thrown. It's also a mess, even though we live in a nice area. I feel like I might have some mental struggles because I just can't focus or get anything done with all this chaos. I've tried to get help in different ways, but nothing has worked. My only way out is to study hard, ace these board exams, and move away for college where I can have some peace. Sometimes I doubt I can even do that. I failed last semester, which finally made my parents see some of what's going on. Even though nothing's changed at home, they've said they're okay if I just pass my exams because they know I'm struggling mentally due to the house environment. I had a three-month break before these exams started, and despite the ongoing chaos at home, I was actually studying well. I thought I'd do great this time, aiming for straight A's in every subject. I was doing amazing until the math exam. I should mention that our education system is really flawed-there are separate pass marks for the multiple-choice and written parts. My written part went well, but the multiple-choice didn't. I'm terrified about my grade and now I'm just hoping to pass. The exams after math went okay, though. Today was chemistry, and again, I'm just praying to pass, insha'Allah. My mom has been sick for three days, so she couldn't drop me off at the exam center-my dad did. When I got home, my brother was yelling at my mom for not cooking for him. I'm just so tired of everything. So many people are expecting me to do well in these boards, and I feel like I'm going to let them all down. If you've read this far, I'm truly grateful. I'm asking anyone who sees this to please, please remember me in your prayers, especially on the Day of Arafah since it's coming up soon. I just want to do well, move out, and get the help I need, insha'Allah.
