Testing 8/27, I’m burnt out.

Hey everyone , just like the title says, I feel like I’m burnt out. I’ve never dealt with this feeling before so I’m not sure how to classify it but it’s honestly along the lines of tired even after 7-8 hours of sleep, lack of motivation, and just so so tired. I took a day off yesterday (did research work , no studying) but as I wake up today I feel the exact same... I have gotten 511/510 on FL1 and 2 but I feel really guilty taking a day off this close to my exam given that I’m not at my ideal score yet. I honestly don’t even know what I’m asking in this post, just needed to vent. Thank You for listening..
