Just two days after announcing the split from her husband David Foster, "The Real Housewives of Beverly Hills" star Yolanda Foster has broken her silence. The former model spoke to Entertainment Tonight and gave an update on how she's handling her pending divorce and also opened up about her ongoing battle with Lyme disease.

"I'm keep going, one foot in front of the other," the 51-year-old mother of three told Entertainment Tonight in a video interview. "I mean, obviously this is a difficult time, I'm heartbroken but I'm grateful to have my job and be dressed up at an event."

She's also grateful for her three children, her supermodel daughters 20-year-old Gigi and 19-year-old Bella, and 16-year-old son Anwar Hadid from a previous marriage.

"My Gigi, my Bella and my Anwar. My forever. I guess that's my only forever," she told People.

She said that a variety of things led to her split from her songwriter/music producer hubby, including work, the children, life and her own ongoing health problems, according to Entertainment Tonight.

"Life is overwhelming for everybody and it's a lot of work to keep it all together," she said.

Foster was diagnosed with Lyme disease in 2012 and has been battling her disease ever since, as previously reported by HNGN. It was in the beginning of her illness where things started to fall apart in her four-year marriage.

But Foster isn't letting the divorce deter her from her goal of ridding herself of Lyme disease, and she's also not worried about her "RHOBH" cast mates who have doubted the state of her health.

"I just have a very laser-beam focus," she told Entertainment Tonight. "All i want to do is get to the finishing line, get my brain back and teach the world a lesson about Lyme disease."
