Struggling with My Academic Journey – Need Advice

Assalamu alaikum, I hope you're doing well. I'm a student and I have to retake my exams for the second time because I didn't get the marks I know I'm capable of. I used to be a really smart student, always topping the class, and now I can't even get close to that. I feel absolutely crushed and my parents are not even talking to me right now, which makes it worse. Islamically, what does this mean? I keep getting tested and I keep falling, but I try to stand up again only to fall back down. It's exhausting. I know Allah doesn't burden a soul beyond what it can bear, but I'm in so much pain inside, it feels unbearable. Why does life keep pulling me down when I try to get back up? I try to be a good person – I don't hurt anyone, I don't smoke, I don't drink – yet I still feel like I'm being punished. I've never felt suicidal, but the thought is starting to linger. I feel so bad for my parents who worked so hard for me, and I bring home terrible results. I did try harder this time; I gave up so much – hanging out with friends, going out with family – to study, and I was somewhat consistent, but my grades don't reflect that effort. I know there's no point crying over spilled milk, but I just don't understand the lesson here. All I get is tests, no good news, no good results. I don't even know anymore. Any advice or comfort would be really appreciated. JazakAllah khair for reading.
