NBC’s Party at THE POOL Celebrating NBC’s New Season – Pictured: Kyle Richards, The Real Housewives of Beverly Hills on Bravo

Kyle Richardshas been finding her way back to normal after the intense day of filming for theReal Housewives of Beverly Hills' season 12 reunion.

TheHalloween Endsstar, 53, is getting real about the emotional toll the Bravo series’three-part specialtook on her and her costars, telling PEOPLE: “It was the first reunion where we don’t go out after and have dinner or grab a drink, or do a group photo or a group hug. There was none of that. So that sort of tells you how it ended.”

Noting that “three weeks after, I’m obviously way better,” she continues, “I was not in a good place for a while after that, to be honest, but I’m slowly coming out of that. And time heals all wounds.”

Adds Richards, “I’m just hoping to eventually get to a better place and put that behind me.”

PEOPLE exclusively shared the season 12 reunion trailer last week, which saw HousewivesGarcelle Beauvais,Erika Girardi,Diana Jenkins,Dorit Kemsley,Crystal Kung Minkoff,Lisa Rinnaand Richards rehashing the drama from the past 21 episodes.

Friend of the Housewives and Richards' sisterKathy Hiltonalso joined taping and got into it with Rinna, 59, regardingwhat Hilton did or did not say during a cast trip to Aspen, Colorado. (Rinna has claimed in previous episodes this season that Hilton, 63,had a meltdownin which she spewed language so hateful about Richards and the other Beverly Hills Housewives that Rinna had to lock herself in her room.)

At the time of the reunion taping, Richards was at a crossroads and feared she’d have to choose between blood and friends, “I need to end up in a better place with her than when she came,” she says of Hilton. “Look where we are right now.”

Elsewhere in the trailer, an emotional Richards also told hostAndy Cohen, “I’m really not okay right now. I don’t want to sit here for a toast. Can I leave?”

A source told PEOPLE over the weekend that Richards and Hilton’ssibling rivalryhas recently come to a head, with the costars bringing “a lot of tense energy” to set.

“They cannot reconcile, and it’s allso complicated because nobody’s backing down. Kyle has backed up her sister for years and no matter what she does, Kathy isn’t satisfied,” the source said. “What we’re watching is years of family trauma that hasn’t been dealt with in a family dynamic.”

Although the sisters have long had a rocky relationship, the insider noted that this moment is “complicated” as it’s the “first time” Hilton’s two daughters,Paris HiltonandNicky Hilton Rothschild, have had to intervene.

“They all grew up together. Kyle acted as a spokesperson for the Hilton family for a long time. They always make up, but this is a little different because Kathy is front and center on camera. She hasn’t been forced to be vulnerable. Kathy and Kyle have spoken loosely via text only since the reunion,” the insider explained.

But not all was so bad during filming of theRHOBH reunion, as Richards tells PEOPLE that her longtime friend andHalloween EndscostarJamie Lee Curtismade a surprise appearance that even she didn’t know was taking place.

“All the ladies on the show love her, they just went crazy over her,” she says. “And Jamie did not know what she was getting herself into.”

Richards also says that although Curtis, 63, “is not somebody who watchesThe Real Housewives” franchise, “she of course sees things online and clips.”

But according to Richards, one of those clips — specifically the reunion trailer — stirred up emotion so visceral in Curtis that shecried and called Richardsafter viewing it.

“She kind of gave me a pep talk about what she thinks of me as a person and not to forget it. And it’s never lost on me that she makes the time and the effort to do that for me, becauseshe always does.”

“I don’t know who made her upset, butI called her out of real concern,” Curtis continued.

For her part, Richards told PEOPLE: “I’m just appreciative” that Curtis “really is” atrue friend.
