Yolanda Foster Says Daughter Bella Hadid Also Diagnosed With Lyme Disease

— -- Yolanda Foster has been open about her battle with Lyme disease, posting pictures throughout the process.

Now, the mother and reality star is opening up about his kids, who have also been diagnosed with the chronic illness.

"When my two youngest children, Bella [age 18] and Anwar [16], were diagnosed with chronic Lyme disease in early 2012, watching my babies struggle in silence in order to support me in my journey, struck the deepest core of hopelessness inside of me," she said at the Global Lyme Alliance gala, according to People magazine.

Foster has been battling the disease for three years now and received an honor at the gala.

"This award is for Anwar and Bella. This is my token and my promise to you that I will not allow you to live a life of pain and suffering. I will walk to the end of the earth to find a cure so that you can live a healthy life that you deserve," she added. "No child should suffer the way that you do ... I thank you both for your extraordinary selflessness during this journey."

The 51-year-old also touched on how the disease took away from her family's quality of life.

"I am so sorry for all the important things I have missed in your life these past four years," she said. "All three of my children really got short-changed with a dumb blonde in the white robe, that mostly lives her life in bed. ... I did turn into a professional social media stalker, though—liking every Twitter and Instagram you have ever posted, just to let you know that I was watching you from afar."
