Yolanda Foster continues to do her part to raise awareness for Lyme disease both on The Real Housewives of Beverly Hills and online.

In a new tweet, which came just days after the mother of three announced plans to write a book about Lyme disease, Foster spoke about the invisible nature of the illness.

Foster also shared a recent post about Lyme disease on Instagram, along with the message, "Its time for a CURE, don't you think?........ #AffordableForAll #ChronicLymeDisease #LymeDiseaseAwareness @lymestats."

While appearing on Watch What Happens Live last week, Foster confirmed plans for a book.

"I just signed a deal. So I am right now trying to find a co-writer to do it with me. And I'll be focused on that for the next six months," she told a caller during the show, according to a report by Bravo TV's The Daily Dish. "I'm excited because I have so much to share. It's been such a long journey."

Foster first announced plans to write a book in February.

"I've been wanting to write a book, obviously, for four years, but haven't had the brain power to do so," Foster told The Daily Dish at the time "I've documented my entire journey with photographs because I learned today's world, everything is kind of visual. People don't really read that much anymore. Pictures really hit home. And it's funny because the girls on the show kind of judge me for posting a picture with an IV, which is nothing compared to the pictures that I have and the story that I have to tell. It's very detailed, it's about all the treatments that I've tried, all the different places that I've been in the world, but mainly it's about my spiritual journey that came with this."
