According to a source who had seen the preview of the documentary series, Justin Bieber had been feeling extremely depressed and lethargic in 2019, having his Lyme disease misdiagnosed as depression.
The most common symptoms of Lyme disease are fever, headache, fatigue and a skin rash called erythema migrans, and can be treated over several weeks with antibiotics.
However, if the infection is left untreated it can spread to the joints, heart and nervous system.
Justin Bieber has addressed his Lyme diagnosis on Instagram, confirming he has been battling the illness for some time.
"While a lot of people kept saying Justin Bieber looks like shit, on meth etc. they failed to realize I've been recently diagnosed with Lyme disease, not only that but had a serious case of chronic mono which affected my, skin, brain function, energy, and overall health," Justin wrote on social media.
"These things will be explained further in a docu-series I'm putting on YouTube shortly," Justin continued.
"You can learn all that I've been battling and OVERCOMING!! It's been a rough couple years but getting the right treatment that will help treat this so far incurable disease and I will be back and better than ever NO CAP."
There are loads of celebs that are currently suffering from Lyme disease (what's up LA?) including Bella Hadid, Shania Twain and Avril Lavigne.
