The ladies of Real Housewives of Beverly Hills are back from their holiday in Paris, but they didn’t leave all of their drama behind in Europe.

In this sneak peek of Season 3, Episode 17, Kyle Richards and sister Kim have a heart to heart during the grand opening of Kyle’s new clothing store called Kyle by Alene Too. The two sit down in one of the dressing rooms, and Kim explains to Kyle that she confused her medications during the trip, which explains her confusing behavior in Paris.

“It makes a lot of sense that she took the wrong medication, because I know my sister has been very strong in her sobriety,” says Kyle in her confessional.

Kyle is relieved, and Kim explains that it’s frustrating that she needs to defend her sobriety, but she understands that she has to earn people’s trust again.

“I worked very hard to get here, there’s no way I want to go through what I went through again,” Kim tells her sister, getting a bit teary-eyed. “I’m sober and I like it, and there’s no way I want to let anybody down that I love.”

Kim admits that she struggled with suicidal thoughts, and Kyle begins to cry.

“Everytime my phone rang in the night, I thought they were going to say, ‘Your sister is gone,’” Kyle tearfully confesses to Kim.
