Yolanda Foster was seen attending a Lyme disease gala on Monday's Real Housewives of Beverly Hills, and in her blog, she opened up about the experience.

After being honored for raising awareness, the reality star revealed her two youngest children, Anwar and Bella Hadid, were also suffering from the illness.

"Watching tonight's episode brought tears back to my eyes. Seeing my children, my mom and friends show up to support me, speak for me and listen for me meant more than words can ever say," Foster wrote in her Bravo blog on Wednesday. "We who suffer from chronic Lyme can only ask for our loved ones to try to understand and be compassionate about this invisible disease. Thank god I am blessed with a small circle that has guided me through these years and never let go."

"Thank you Gigi for your beautiful speech! Thank you for exceeding every hope, dream and expectation I ever had for you. I am so proud of all that you do and all that you are," Foster continued. 

Speaking of her struggles, which have continued since her 2012 diagnosis, Foster told fans, "I honestly don't have the proper words in my English vocabulary to describe to you the darkness, the pain and the unknown hell I've lived these past four years. I actually did not live, I just existed in the jail of my own paralyzed brain. This disease has brought me to my knees. Many nights I wished to die and prayed I would just wash away into heaven where there would be no more pain. But God had different plans for me, he changed my destiny when my two youngest children Bella and Anwar were diagnosed with chronic Lyme disease."

"Watching my babies struggle in silence while supporting me in my journey struck the deepest core of hopelessness inside of me, and it is because of them that I am motivated to stand here in front of you today," she added. "I do NOT deserve this award... This award is for Bella and Anwar. This is a token of my promise that I will not allow you to live a life of pain and suffering. I will prevail and walk to the end of the earth to find a cure so that you can live the healthy life you deserve."
