Justin Timberlake‘s taking a load off after getting done touring and announcing he has Lyme disease … and his sweatshirt says it all.

The singer just posted to his Instagram Story on Monday … and he’s rocking a gray sweatshirt that reads, “I’m not doing s*** today.”

Justin’s top also says … “Mission accomplished” with a green check mark. He added some check mark emojis to his post.

Justin announced his diagnosis last week after his tour ended … though he said he wasn’t looking for any sympathy.

He’s been super busy for the past couple years … dealing with an arrest in the Hamptons and a social media obsession with his bulge.
