Yolanda Foster is having a rough few months. In addition to announcing her split from David, the reality star is still battling Lyme Disease -- and so are her children.

Foster's youngest two children Bella, 19, and Anwar, 16, are all battling the autoimmune disease. The trio were diagnosed in 2012, but it was only in October that Foster announced Bella and Anwar's struggle at the Global Lyme Alliance gala.

The Real Housewives of Beverly Hills star has been keeping fans abreast of her treatment via Instagram and now she's letting followers in on her daughter's treatment and struggle.

On Tuesday, Foster posted an image lying in bed with her daughter, who is hooked up to IV treatments. The photo is from 2015 and shows the teen looking like she's in a lot of pain. Quite a far cry from yesterday's images of the supermodel strutting her stuff at the Chanel show during Paris Fashion Week.

Foster captioned the image, "Watching my brave babies stuffer in silence in order to support me in my journey has struck the deepest core of hopelessness inside of me, it is because of them that I continue to fight relentlessly. I will not allow them to live a life of pain and suffering."

We think it's a bit odd that she's putting up this photo of her daughter -- who looks like she is suffering -- especially given all the criticism she's gotten over her Lyme Disease and her constant posting about it. While we (and many others) may be critical of the reality star -- there is one person who has her back, her ex Mohamed Hadid. Gigi, Anwar and Bella Hadid's dad defended his former spouse in a rare Facebook.
