What should I Do?

I struggle with the same problem, and one thing I've found helps me a lot is staying away from all forms of social media while studying.
If it's mostly your phone that's distracting you, put it in another room. If it's something on your computer, use someone else's (maybe go to a public library and use those of they have any).
You won't need to cut it out of your life entirely, just when it's becoming a problem.
