Yolanda Foster on her Lyme disease: 'I just pray every day'

There were many tense, claws-out moments on the "Real Housewives of Beverly Hills" season five reunion, but Yolanda Foster's upsetting update was not one of them.

"You had a serious relapse with your Lyme disease. Tell me what your life is like day-to-day," said Andy Cohen on "The Real Housewives of Beverly Hills" reunion.

"Do you really want to talk about that? Um, you know, just trying to weather the storm, you know? I just pray every day that maybe tomorrow is a better day, you know?" Foster said.

As Andy Cohen said, Yolanda's Lyme disease relapsed in December of last year, and it has been taking quite the toll on her ever since.

In fact, the housewife was feeling so ill during the reunion, she had to leave early to get some rest.

As she revealed in her Bravo blog earlier this year, "I have lost the ability to read, write, or even watch TV. ... It feels like someone came in and confiscated my brain and tied my hands behind my back to just watch and see life go by without me participating in it."

Yolanda was first diagnosed with the disease back in 2012. She and her family have gone to great lengths find a cure, even traveling to South Korea for specialist treatments that she says cannot be administered in the US.

Even though Yolanda is struggling as of late, her husband David Foster told People he has faith she will win her battle with the disease. "She's a soldier. She's a warrior so she's going to beat it."

Just hours before the reunion aired Tuesday, Yolanda posted a photo of herself holding flowers from a well-wisher on Instagram along with the hashtag #MyHealthJourney.

It's unclear what Yolanda's next course of treatment will be, but we wish her all the best.

The reunion was pretty rough for Brandi. Take a peek at some pics from part one:
