Feeling like I can’t go on anymore

Assalamu alaikum. I’m really struggling to find the will to keep going. I’m not the brightest student, and I don’t feel like a good daughter either. Being the eldest in a desi household comes with so much pressure. I try so hard in my studies but I just fall short, and I can’t tell if something’s wrong with me or if I’m simply not capable. My A Level results just came out and they’re really bad. I don’t know if I’ll ever get anywhere in life. My parents are obviously disappointed, but they’re still trying to be supportive. Seeing my mom cry because of me shatters something inside. Sometimes I think about ending it all, but I’m terrified of the punishment in the akhirah. I don’t want to cause my parents more pain. They keep being there for me, yet I keep letting them down. I’ve made so many duas, but things just seem to get worse. I’ve lost any desire to keep living. I don’t know what to do. I have no one to talk to, and I don’t want to burden anyone with my struggles. “Indeed, with hardship comes ease.” But right now, I don’t know how much more I can endure.
