There was an extreme amount of drama on this week's Real Housewives of Beverly Hills. But the only drama that Yolanda Foster is focused on at the moment is the kind that really matters.

Yolanda is battling Lyme disease, and she took to her Bravo blog to say that she is having a tough time with her treatment and is unable to weigh in on this week's episode.

"Unfortunately, I won't be able to write a blog as my brain is out of order at the moment," she writes. "I have started a 20-day intense treatment to try to repair the damage the Lyme has caused neurologically."

Yolanda says that she feels even worse than she did before the treatment. "Unfortunately, I am experiencing worse symptoms than before the treatment started," Yolanda says. "But I was promised that it would get worse before it gets better."

"My apologies for not being able to pull it together  hope to be back at it next week," she adds. "I hope your decorations are up and you are enjoying the spirit of the holiday season."

There's no question that Yolanda is doing her best to fight this disease, and we wish her and her family all the best.
