'KUWTK': Kim Kardashian Feels Like A 'Failure,' 'Loser' Over Kanye West Marriage Breakdown

Kim Kardashian broke down over her marriage problems with Kanye West in the latest episode of "Keeping Up With the Kardashians."

During Thursday's episode of "KUWTK" — part one of the series finale — the Kardashian-Jenner family headed to Lake Tahoe for one last family outing for the show. Kim immediately became upset over a plate of cookies in the kitchen, saying she wanted them to be taken away.

"Where's my room? I just want to go to my room and never come out," Kim said after snapping at her family.

Her sister, Khloe Kardashian, shared in her confessional that Kim has been "struggling privately behind [the] camera about her relationship."

"It's tough because Kim is clearly redirecting so much of her frustration and sadness and anger. And, you know, sometimes you just take things out on something that has nothing to do with what you're going through. It's not the cookies' fault," she continued.

At the time of filming, Kim and West were still together. But in February, the Skims founder filed for divorce from the rapper, with whom she shares daughters North, 7, and Chicago, 3, and sons Saint, 5, and Psalm, 2.

The aftermath of a fight between Kim and West prior to leaving for Tahoe was also shown during the episode, When the sisters sat down to talk later, Kim cried as she told them she "can't do this anymore."

"Why am I still in this like, place where I'm stuck for years?" Kim told sisters Khloe, Kourtney Kardashian and Kendall and Kylie Jenner through teams. "Like, he goes and moves to a different state, every year, I have to be together so I can raise the kids, you know? And he's an amazing dad, he's done an amazing job …"

Kim continued, "I think he deserves someone that can go support his every move, go follow him all over the place and move to Wyoming — I can't do that. He should have a wife that supports his every move and travels with him and does everything."

"I feel like a f------ failure, that it's like, a third f------ marriage," Kim added. "Yeah I feel like a f------ loser. But I can't even think about that like, I want to be happy."

In her confessional, Khloe praised Kim, describing her as "one of the most incredible human beings" she has ever known.

She also said her sister has done her best to "protect" their marriage, "but it's hard when you carry that responsibility on your shoulders and I just want her to take care of herself too."

Kim is expected to open up more about the end of her marriage in next weeks' finale of "Keeping Up With the Kardashians."

Kim was previously married to music producer Damon Thomas from 2000 to 2004 and former NBA player Kris Humphries from 2011 to 2013. She tied the knot with West in 2014.
