In a tough spot and I don't think I can crack JEE.

So, the past two years grind has been weird with ups and downs but I never excelled, no matter how hard I worked. It was fine, though, I was trying. Until shit hit the fan, a major operation happened, nearly died, landed in ICU, was admitted into hospital for half a month and nearly 1.5 months went to drain due to health conditions (october-november time). Was not going to coaching ofcourse, couldn't open a single book and find will to study (I needed help for even going to bathroom and washing hands oop). All the momentum broke. I started trying to cover up the final chapters, as the recovery began, of 12th syllabus that I had missed out in these months. Tried hard. Still am trying so hard to do anything. But now as I give part tests for 11th syllabus, my scores don't even enter the three digits. Below 100 and its just so so fucking scary. All my friends say 'oh god, i bombed the test' and then I ask them how much they scored-- 190. 200. 230. And I start feeling pathetic. Yeah yeah, they say I had my health conditions blah blah but I still wanna do good man. I still want to make something out of this work I am putting in but... it just isn't amounting to shit. Not like I was excellent before, but now I am just... terrible. A failure. Nothing. JEE isn't the end of the world, but it is the end of the tunnel these two years were-- and its gonna amount to what... a failure. Anyways, tips on how to practice maths pyqs and do organic chem?
