I had this whilst studying for my exams last year. I began meditating through the headspace app and it really helped.

It's basically just listening to a 10 minute audio and thinking.

If you can sit down/lie down and listen to the audio for 10 minutes everyday, you'll sharply improve your concentration. You're training yourself to become comfortable with being bored.

However, this is just my personal experience, everyone is different.
