At 31 years old, Khloe Kardashian is living on her own for the first time in her life.

The reality star reveals both the best and worst thing about having her house to herself in a post on her app on Monday, and admits that she definitely misses her younger brother, Rob Kardashian. Rob was living in Khloe's house before their mother, Kris Jenner, bought him his own $2.3 million home in February in an upscale gated community in Calabasas, California.

"When Rob lived with me, we would watch movies or TV," Khloe shares. "We'd eat together and talk about stuff that happened that day. I miss those things. It's a big house, so to combat lonely energy, I play music and light candles."

"The worst thing about living alone ... is that I'm alone!" she also writes. "My house is filled with people during the day. After they leave, it's quiet."

According to Khloe, she now has to force herself to go out.

"I am too content being alone," she says. "I could stay at home all day. I have to MAKE myself go socialize."

Still, there are some pros to living by herself -- namely, having the freedom to go naked.

"I love living alone because I am a loner by nature," Khloe explains. "The best thing about it is that I can literally just run downstairs naked and don't have to think about it. I couldn't do that before, with Rob and his friends who would come over. I really like having 'me' space."

Rob's big move earlier this year definitely came with its fair share of drama. Last month, a hurt Khloe refused to help her 29-year-old brother move into his new home during an episode of Keeping Up With the Kardashians.

"I am the only one that stood by him and defended him and wanted the best for him," Khloe said, explaining why she was frustrated at Rob for essentially cutting ties with her after striking up his relationship with his now-fiancee, Blac Chyna. "I would have such deep fights in my family because I was 'enabling' Rob by letting him live with me. The one person who yelled at me the most [was] my mom. Now she's helping Rob? I just find it mind-blowing."

"He hasn't called to check on me or to say hi or 'I miss you,'" she added, opening up to her BFF, Malika Haqq. "He's lived with me for how many years and he's just OK just completely leaving and not saying a thing to me? That hurts my feelings."

But in April, Kris defended her decision to buy her son a house next to Blac Chyna. When her daughter, Kim Kardashian West, heatedly told her, "You should not be paying for your son that is almost 30 years old to buy a house," during a tense meeting on KUWTK, Kris responded by calling out Kim's own questionable life choices -- namely, her short-lived marriage to NBA star Kris Humphries.

"I've seen you guys through so much s**t that you, that I have to f**king put up with," Kris retorted. "'I'm married for 72 days.' Really, that's normal?"
