According to Justin's Instagram post, he's been dealing with a Lyme disease diagnosis and recently suffered from a "serious case of chronic mono" that affected his "skin, brain function, energy, and overall health". The original TMZ report shared that Justin was releasing a documentary in which he would discuss the scary symptoms that sent him to the hospital and how doctors couldn't figure out what was wrong until late in 2019.

The report also gave some clarification on photos that were taken last year of him crying and others with an IV in his arms. He reportedly dealt with severe depression from his symptoms and the IV was for Lyme disease treatment.

The "Yummy" singer also clarified in his post that it wasn't just the Lyme disease making him ill. He was also dealing with a very severe resurgence of chronic mono.
