Struggling with heaviness while trying my best – need your duas

Assalamu alaikum everyone, I don't usually open up like this, but I could really use your duas right now. I'm getting ready for my CBSE grade 12 physics improvement exam, and it’s a big deal because my university admission hangs on it. Alhamdulillah, I finally found a good teacher, and for the first time in a long while, I actually get what’s being taught. I’ve been taking notes, practicing questions, and truly putting in the effort. But even with all that, there’s this weird heaviness inside me that I can’t explain. It’s like a constant pressure on my chest and mind. I wake up tired, my body feels drained, and when I try to study, it’s a real struggle to push through. It’s not that I lack motivation-I really want to do well. I just feel worn out in a way words can’t capture. Some days bring hope, and other days I feel like breaking down even while I’m studying. I keep making dua and trying to trust Allah’s plan, but I’d be so grateful if you could also make dua that Allah lifts this heaviness from my heart, gives me strength, makes studying easy for me, helps me remember what I learn, grants me success in my exam, and opens the doors that are best for my dunya and akhirah. Jazakum Allahu khairan. May Allah accept all your duas and ease everyone’s struggles. Ameen.
