On this week's episode of Real Housewives of Beverly Hills, Kyle and Kim Richards watch Lisa Vanderpump faint on Dancing With the Stars, and instead of seeming concerned, they immediately assume Lisa is faking it. Now, Lisa is speaking out about her collapse.

Lisa explains in her Bravo blog that she has had health issues over the years that sometimes cause her to pass out. "Over the last few years, my health has been checkered with anemia and dizziness and a few fainting spells," she writes. "I am fit, as I work out every day, but chronic anemia and dizziness has been an issue."

"That week after the Monday and Tuesday on DWTS, which in itself was exhausting, I did all the press line (normally a couple of hours), then took the red-eye with Gleb to New York," Lisa continues. "We arrived having missed a night's sleep and had to go straight to a six hour rehearsal, then had to attend a party for Bravo and finished work at almost midnight," followed by only a "few hours" of sleep.

"The next day, I was feeling wobbly," she adds. "Yes, I fainted. We went to the doctor (unfortunately with the cameras) and he diagnosed a plethora of problems: low blood pressure, swollen glands, fever, and exhaustion."

Lisa says the she was hurt but not surprised to see Kim and Kyle laughing about her fall. "Now, how do I feel when I see the Richards sisters mock me?" Lisa writes. "Not great, but sadly... I don't expect anything less."

Lisa also points out that, until Kyle and Kim visited her — with Bravo's cameras — on DWTS, they hadn't showed their support. "Until then, Brandi [Glanville] was the only one who had come to support me or tweeted," Lisa says.

We're glad Lisa is feeling better these days, and we can't wait to see the continued drama between Kyle and her.
