Yolanda Hadid is writing a book about her battle with Lyme disease.
The 52-year-old reality TV star - who is the mother of models Gigi and Bella Hadid - will release 'Believe Me: My Battle With the Invisible Disability of Lyme Disease', which details her life since her 2012 diagnosis, in February 2017.
Her publishers St. Martin's Press said in a statement: "While doctors continued to dismiss her pain and friends debated about her health diagnosis, Yolanda realised her mission and higher purpose of her journey is to use her newfound platform to educate, and bring awareness to the stigma surrounding chronic Lyme in order to bring hope to other sufferers who have been misdiagnosed and battling the invisible disability of chronic disease in general."
Yolanda's children Bella and Anwar have also been diagnosed with the disease and the 'Real Housewives of Beverly Hills' star previously claimed her diagnosis changed the "dynamic" of her relationship with husband David Foster - who she split from in December.
She said: "We had a beautiful love story that I will treasure forever. Unfortunately, it was not strong enough to withstand the circumstances that came our way.
"Chronic, long-term illness is extremely challenging. Not only for the person sick but also for the caregiver. It for sure changed the dynamic of the relationship.
"The truth is that we both worked through the difficult time through the best of our ability, so rather than judging what went wrong, I pick to remember the great times that we shared the last nine years. There was a wealth of good times."
