Kendall Jenner writes down her thoughts in a diary she keeps under lock and key, and it has been beneficial for her mental health.

The 26-year-old supermodel shared during an interview with i-D that writing in a diary at least once a week has helped her regain a sense of privacy. She also said the habit helps quell her anxiety, panic attacks and even "a little bit of depression."

"It's important to have a space that's just for you where you can let out your happiness, your anger, frustrations, and stress, the things that are freaking you out, the things that are making you happy and even just ideas," she explained.

What goes into her diary is a secret — one that only Jenner knows. "Yeah, it's like an old-fashioned diary. It has a lock on it and I hide it, I lock it away: mine is so, so secretive. I'm like, 'No one can ever get this,'" she added.

Besides keeping a diary, she also reads to remain calm and think clearly. "I was having a panic attack two nights ago, and I was just like, 'Oh, but you know what? I'm just going to pick up this book and try to forget,'" Jenner continued.

According to the "Keeping Up With The Kardashians" alum, reading is a "great form of therapy and form of distraction."

"I just love having things that are for me and no one else, you know? I feel like reading is one of those things," she said further.

Jenner has been in the limelight since she was very young, and trying new things amid all the public attention she receives has certainly helped her. "I used to be really angry," she revealed. "I mean, you can literally find old videos of me screaming at the paparazzi for no reason, but also for a very obvious reason. I'm just a lot more at peace with things now. It's hard to explain… it's just something that you learn to live with, I guess."

The model then opened up about accepting new challenges and endeavors, saying, "It still feels like I'm not fully formed, but with every chapter, I become a little bit more fulfilled."

"It's a sad thing to say, but sometimes you almost have to remind yourself who you are. I think doing your own personal work is a really great way of reminding yourself, 'Oh, no, no, no, no. This is who I am," she said.

Fans can recall that in May 2021, Jenner opened up about how "being overworked" led to her panic attacks. "I remember being really young and having shortness of breath and going to my mom and telling her that," she said in a four-part video series called "Open Minded," according to Vogue. "In hindsight, now I know that that was obviously anxiety," she added.
