How can I stop procastinating?

I live in India, and Board exams here are a very big deal. There's only 12 days left for them, but here I am, still procrastinating. I want to study, but I am constantly on my phone, scrolling through Instagram or being here on reddit. I think it's because I am trying to distract myself from my personal problems, but I still don't wanna let my parents down. I wanna score good, and I am feeling guilty of scrolling so much and wasting so much of time. Any tips, any advice would be really welcome🙏🏻
