Yolanda Hadid has been battling chronic Lyme disease since her diagnosis in 2012, and says she will try anything to get better.

“I’m like a little scientist at work,” the former Real Housewife of Beverly Hills, 52, tells PEOPLE. “I want to figure this out. I want to be 100 percent functioning like a normal person. I deserve it, I want it and I’m going to get it.”

As part of her plan to beat her disease, Hadid, who is co-chair of the Global Lyme Alliance’s annual “United for a Lyme-Free World” Gala, has been sticking to a “very extreme diet.”

“Right now I am no gluten, no dairy, no grains, nothing that turns into sugar, no caffeine, no alcohol, no black tea,” she says.

“It’s boring, but I would eat bark for a year if it would save my life,” continues Hadid. “I’ll do anything.”

Hadid — whose memoir about her struggle with Lyme disease is due out in February 2017 — has documented her ups and downs with Lyme on social media and on The Real Housewives. Last October, she revealed that her daughter Bella, 20, and son Anwar, 17, also have the disease.
