This poor family!

Real Housewives of Beverly Hills star Yolanda Foster has been bravely battling Lyme disease for several years, and at last night's Global Lyme Alliance Gala in New York City, she revealed that her daughter Bella and son Anwar are also struggling with the autoimmune disorder.

"When my two youngest children, Bella and Anwar, were also 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," the reality star told the crowd.

"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. No child should suffer the way that you do. I thank you both for your extraordinary selflessness during this journey. Your unwavering love and compassion has kept me alive and fighting through the darkest days of my life," she continued during her emotional speech.

Daughter Gigi Hadid and boyfriend Joe Jonas were on hand to support the model's relatives, and Yolanda's husband David Foster was in attendance as well.

Bravo to these fighters for raising awareness for an important cause!
