In an April 2021 interview with Health, Christina spoke up about her mental health issues. "I experienced a lot of trauma in my childhood—I've spoken very openly about it," she said. "But I think that was just part of my path. I've definitely had struggles in the past with depression and anxiety—it's a constant battle to overcome a mind that is anxious, a mind that is always second-guessing."

Many people strive to be skinny, but Christina wants everyone to know that it's not all it's cracked up to be. In fact, when she was her skinniest, she was also the most insecure. "I think we all have our good days and our bad days in how we feel about ourselves. Entering this business, I hated being super skinny," she confessed. "Once I turned 21, I started filling out a little bit, and I was loving my new curves. I appreciated having a booty. I've always said that women are way more interesting to look at than men! I have a hard time looking at the early pictures of myself because I remember feeling so insecure. I would never want to relive my 20s—you're so in your own head and finding your confidence. As you age, you stop comparing yourself to other people and start appreciating your own body and owning it."

Christina stresses the importance of working on yourself. "I'm proud of my honesty. It's a really hard thing to stick to in this business, especially when you've grown up under a microscope at a time when society was very critical of young women. I've had to work through a lot of insecurities in front of everybody," she said. "Every setback has catapulted me forward. I think that's my fighting spirit. And, at the end of the day, living that truth and being honest has always propelled me forward." 

Christina maintains that true happiness comes when you live for yourself. "You start asking yourself: 'Why am I holding back in certain areas of my life? Who am I really living my life for?' And with age, you figure out that life is too short to waste time thinking about what other people think about you. I've realized I am making memories for myself and that I shouldn't worry about what other people think," she explained.  

There is power in vulnerability, per Christina. "You know, I've been hearing that a lot lately because I've been super open and vulnerable. I've been approaching all of my writing sessions by being an open book and saying, 'Look, this is how I felt.' A lot of people have been like, 'Wait, I had no idea you ever felt this way because you've always been a pillar of strength with your messages.' Yes, I've always been grounded in knowing myself. But even in owning your truth and power, there are moments of weakness. I am not ashamed to say that I have my dark moments," she said. 

Christina focuses on "grounding and centering" like writing and spending time in nature. "Also, getting outside helps—even if it's just my backyard. Feeling grass under my feet and looking at trees and clouds helps," she said. "Yoga has also been instrumental in helping me."
