While Kelly Osbourne is definitely up-front about her opinions and appears to be pretty unabashedly open about her life, it turns out that she鈥檚 been suffering from a life-threatening illness (the very same chronic condition that Bella Hadid has been struggling with) that has mostly kept her out of the spotlight and went misdiagnosed for a full decade.

In excerpts from Kelly Osbourne鈥檚 new memoir, There Is No F*cking Secret: Letters from a Badass Bitch, shared by Us Weekly, the 32-year-old celeb revealed that she has Lyme disease, which she contracted back in 2004. When her mom, Sharon, gifted her father, Ozzy, with a reindeer sanctuary in the backyard of their home in England, Kelly was bitten by a tick. Though her dad burned it off, the bug still managed to infect her with the illness.

However, it was 10 years before Osbourne would find out what she was suffering from. As she battled 鈥渢raveling pain,鈥 a sore throat, and stomach aches, she was eventually diagnosed with epilepsy after having a seizure while filming E!鈥檚 Fashion Police in 2013. She reveals, 鈥淭he doctors kept changing my prescription, trying to get the dosage right, and it turned me into a zombie鈥 My prescriptions kept piling up.鈥

She continued, 鈥淚 couldn鈥檛 sleep, so they gave me Ambien. When Ambien made me nauseated, they switched me to Trazodone, but that gave me acid reflux, so then I had to take an antacid every day. I took cranberry extract and antibiotics because one medication made me prone to getting urinary tract infections. Painkillers 鈥 for an ex鈥損ainkiller addict 鈥 to help with the head and body aches. Not kidding 鈥 I had pills to deal with the anxiety that I was having from taking so many pills.鈥

Finally, Kelly sought out a different kind of treatment, saying that as a last resort, she called Philip Battiade at Infusio, an alternative medicine practitioner. She explained, 鈥淚鈥檇 first met him when he treated my brother for MS. When I met with Philip, I assured him that I hadn鈥檛 used unprescribed drugs in years and that I thought I had Lyme disease鈥 For the first time, someone listened to me, and I got tested.鈥

They found pretty much exactly what Osbourne was expecting to find. 鈥淭he results were positive: I had stage III neurological Lyme disease.鈥 But the struggle didn鈥檛 end there, with the celeb revealing, 鈥淚 was relieved to finally know what was going on, but I was also scared sh*tless鈥 I was experiencing emotions and feelings again. I鈥檇 been in a diseased and doctor-approved drug-induced haze for so long that I didn鈥檛 know what it was like to be happy or sad or in pain.鈥

She also revealed why she hasn鈥檛 talked about her diagnosis before this, saying, 鈥淚鈥檝e kept quiet about my Lyme disease, not only for fear of pharmaceutical companies coming after me because of the cure I found in Germany but also because it seems like the trendy disease to have right now, and I鈥檓 tired of seeing sad celebrities play the victim on the cover of weekly mags. Since I know firsthand how awfully debilitating it is, I know who really has it and who is just trying to prolong their 15 minutes. I don鈥檛 understand how anyone could think that the life you have to live with Lyme disease is glamorous.鈥

We鈥檙e just happy to hear that Kelly Osbourne is doing better these days and hope she continues to reach her goal of better health.
