RHOSLC's Whitney Rose Shares Update on Daughter Bobbie, 14, After Health Scare: 'She Is a Fighter' (Exclusive)

Whitney Rose is sharing an update after her daughter was rushed to the hospital last month.

While speaking exclusively to PEOPLE, the Real Housewives of Salt Lake City star, 38, said her 14-year-old daughter Bobbie is a "fighter" and is "doing so much better" after she was taken to the intensive care unit (ICU) in an ambulance while suffering from "severe asthma exacerbation."

"That health scare with Bobbie was one of the most terrifying, hardest things I've gone through as a mom with my kids so far," the reality star — who shares her two kids, Bobbie and 11-year-old son Brooks, with husband Justin Rose — tells PEOPLE.

"It was really terrifying watching her fight for her life," continues Whitney, who first opened up about the health scare on her Instagram Stories Oct. 6. "But she is a fighter and she is strong and healthy. She's recovering and she's doing so much better. She's home."

Whitney says the family has "had to change up some things in our life to make sure that her asthma never gets triggered that badly again," but assures fans her daughter is getting better.

"She's a freshman. She is the best," the TV personality says. "Boys are starting to come around. She steals all my makeup, all my new clothes. Yes, I feel like I just have a better version of me, and watching her grow up is one of the coolest things I've ever done."

Whitney adds of her son, "Brooks is 11. He's in sixth grade, so my last year with elementary ... [but] they're thriving. They're both killing it in soccer, slowly getting better at soccer."

The Bravo star's comments come after she revealed on her Instagram Stories Oct. 10 that Bobbie was out of the ICU and "recovering at home" following the health scare.
