"Real Housewives of Beverly Hills" star Kim Richards sat down with ET on Wednesday to address her struggles with sobriety, the now-infamous Dr. Phil interview, and what really happened the night she was arrested for public intoxication at the Beverly Hills Hotel.

"I love sobriety," Richards told ET's Nischelle Turner. "I've always loved sobriety, and relapsing was very hard for me. It was not easy. I have to say, don't take this wrong, but I really wanted to go to treatment because I needed a break from what I was going through at home."

Richards cited family stress as a contributing factoring to her arrest, telling Turner, "Monty, my ex-husband, is very sick and my son wasn't well. And I had to give away my dog, and I wasn't talking to my sister [Kyle Richards]."

Richards says she has completed her treatment program and has been sober for more than 30 days. 

"I went in and I got to learn a whole lot about myself," she told Turner. "I dug deep into my past, things that happened to me as a child, good and bad, teenage years, relationships with all my loved ones, where they need to be mended, where they're very powerful. I worked on me."

NEWS: Kim Richards Reportedly Checks Back into Rehab

Richards entered rehab for the fourth time earlier this year after being arrested on April 16 at the Beverly Hills Hotel, following an incident. According to the Beverly Hills Police Department, Richards was acting belligerent and refused to leave the hotel’s restaurant, locking herself in the bathroom. Once taken into custody, she reportedly kicked a police officer in the leg. The reality star was charged with public intoxication, trespassing, resisting arrest and battery of a police officer, and issued a citation for a misdemeanor.

When Turner asked if the arrest was Richard's "a-ha" moment that led her to seek treatment, the reality star admitted, "Actually, my arrest was my 'a-ha I get to go away now and rest and take a break from all this.' I don't want anybody to take this wrong, but I truly needed a break from hospitals, family, the pressure. I needed to go away."

Days before Richards’ most recent rehab stint, she walked out of an interview with Dr. Phil after becoming increasingly uncomfortable with his questions about her arrest.

In ET’s exclusive sit-down, Richards opened up about her plan to stay sober since she left treatment, which includes a "wonderful" sponsor, a life coach, and "a great home group and sober friends."

As for a possible "Real Housewives" return, Richards told ET that she hasn't spoken with producers about coming back to the show because she's been focusing on her treatment, but she revealed that they’ve expressed interest in having her back next season. "My representative did speak to them," she said. "They have asked me to come back."

"I decided to stay in treatment," she told Turner.
