You know, I did this years ago, even before mental health was like a topic among everyone's mind. It was like, all right, I'm shutting myself down today, just subconsciously and it is something I've always done," Serena Williams said."Now that I know that it's so important to just put yourself first, especially mentally. I always have shut down moments. I have serious boundaries and I don't let anyone cross them.""I really don't do anything for me and I'm terrible at that. Time and time again, I said, I'm working on it but more or less, at least prioritizing what I need to do and then when I'm turned off, I'm turned off," she added.The 23-time Grand Slam champion went on to speak about the intensity and passion that goes into everything she does, adding that prayer helps ease her anxiety."I'm a high-strung individual and what I do like you can see. When I'm in my job and I'm playing tennis, I'm really super intense but that's my passion and that's kind of how I wear it even in VC," she continued. "So I do have a tend to become anxious. But I really learned over the past that for me prayer works a lot, just really realizing the bigger picture and it really has helped in my anxiety," she stated.Also Check Out: Reilly Opelka parents
