any tips for getting out of burnout?

In these past couple of weeks I have felt super demotivated and even though I know that I need to revise I just can’t seem to do it. This is coming from someone who spent 5 hours revising every single day for 4 months before GCSEs and has never once struggled to find motivation to study.

I have no idea why this is happening lol. So can someone please give me some tips on how to get of this burn out haha (i need to lock in)
