ForTeddi Mellencamp Arroyave, competing onCelebrity Big Brother"was unbelievably hard."

TheReal Housewives of Beverly Hillsstar, 40, opened up about her experience on season 3 of the CBS reality show on the latest episode of thePEOPLE Every Daypodcast, noting that being away from her family was particularly taxing on her.

Though she only spent 10 days in theBig Brother house, Mellencamp was away from her children for 18 days for the show. To help herself cope, the reality star told host Janine Rubenstein that she “had to really compartmentalize my brain.”

“Anytime somebody wanted to talk about the kids, I could only talk about them a little amount because I didn’t wanna start crying and take myself to really going there — because you don’t get any communication [with the outside world],” she explained.

Mellencamp was the first celebrity evicted onCelebrity Big Brother 3, allowing her to reunite with her family on Saturday. The television personalityshared an emotional videoof her reunion with daughter Dove, who turns 2 on Feb. 25, on Instagram the same day.

In the caption, Mellencamp said she is “so appreciative to be home and will never take for granted how incredible my life is,” adding, “I missed my family and friends more than I ever could have imagined.”

On thePEOPLE Every Daypodcast, Mellencamp noted that she was not the only houseguest that struggled emotionally in the house. Some celebrities, she claimed, simply “didn’t want to be there” and “were really struggling, you know, mentally and physically.”

One of those competitors,Chris Kattan, exited the game Wednesday night, Mellencamp alleged. (NeitherBig Brothernor CBS have confirmed Kattan’s departure as of publication.)

“I love Chris Kattan, but ultimately you knew it was not something he was loving every second,” she said. Mellencamp then criticized the remaining houseguests for not voting him out the week prior, per his wishes.

“The fact that she [Miesha Tate] would choose to boot out a true competitor [Mirai Nagasu] who was doing all right in the house over somebody who you could tell was really struggling and missing their girlfriend or missing their boyfriend or whatever,” she said, “it was was … not the way I would’ve played it.”
