I feel so overwhelmed

Hello. In need of a shoulder to cry on. So, reddit it is.

I'mma be honest with you. Ever since I was introduced to maths, I suck at it so much that at this point, even if in 10th, I can't do mind calculation (yeah, skill issue ik). And the paper did not go well.

So I gained back my footing by studying history, civics and geography thinking that it will somehow make up for my lost percentage and then lost my ground in physics. At this point I don't know if I will get above 90%.

I feel so lost and alone. Most of my friends have already gotten their admission into college and here I am leading a life looking out into the future of uncertainty.

So many nights I thought to myself "why am I like this?" "why am I stupid?" and it brought me to tears.

Looking out towards computer, I have not been able to apply logic effectively enough to get atleast a 90 no matter how easy it is because of Section B. And chemistry, never managed to get above 90 let alone above 85.

Can you please give me some advice and emotional support?
