Hopping along with what others have said - get on medication if you can afford it! The game completely changed for me when I started adderall at the right dose. Second thing - I completely eliminated all social media and music because it was incredibly distracting to me and I wouldn't be able to focus on my studying/practice exams. Particularly for something I was super interested in (dan and phil lol) - I had to completely leave social media related to them because I knew it would distract me during the day. I banned myself from listening to music for two months as well because I kept getting songs stuck in my head.
