Guys what do i do?

I can’t study even when i have enough time for the exam. I am stressed too much. How do i stop the anxious depressive thoughts i have when i sit down to study.

I put on the pomodoro, when i encounter something difficult, my mind shifts to hopelessness. I start binge watching mindless stuff, and get back to studying when it’s too late.

Suppose i have 4 days exam holidays, i do this for 3 days, and cram the last day, which makes me unable to finish the syllabus. I know i will fail the exam and don’t even give the exam. I feel helpless and weak.

What do i do to stop this destructive loop? What habits should I develop? How do i start studying seriously? What mindset do i need? Do i require some kind of medication? What do i avoid to be able to study with a calm mind?

I have double digit backlogs? I have passed only two in a whole year, yeah in 12 months i passed two.

I am desperate for a solution.
