That is such a frustrating position to be in. I agree with NickRowler that going somewhere like the library to study might help. Sitting at home with all of your youtube videos, tiktoks, video games, comic books, art projects, chores within reach can be very distracting, so putting yourself in a more work-friendly environment might help.
Seeting a timer is another strategy. If you're really struggling to read your book, set a timer for just ten minutes, and try to focus as much as possible during those ten minutes. Then you can take a quick break and check your phone or whatever you want to do. Don't beat youself up if you still get distracted, just keep trying even when progress is slow.
If you're food motivated, promise yourself a little treat as a reward for finishing today's reading goal. Be that opening that bag of chips you have or getting something from a café.
You can also see if any of your classmates want to study with you. In a zoom/discord call or at the library. It might be that they're also struggling and you can help each other focus or discuss the text if it's hard to understand it.
