Kate Middleton isn't just a member of the royal family with great hair and style. Ever since marrying Prince William, the Duchess of Cambridge has been using her newfound power to make an impact.

Just like her late mother-in-law Diana, Kate has been appointed patron of a variety of NGOs and charities and she's been doing her best to successfully fulfill her role.

Along with the princes William and Harry, Kate has been a strong advocate for eliminating the stigma around mental health. Last year they spearheaded the Heads Together campaign to create conversation around the issue and help raise funds to improve treatment options.

Now, after weeks of shying away from the limelight, the patron of the mental health charity Anna Freud National Centre for Children and Families is once again stepping in front of the camera to speak out about the importance of talking about feelings, no matter how big or small.

The candid PSA is a rare chance to hear a usually camera-shy Kate talk about a cause near and dear to her.

The video, which was reportedly shot in January, was released on September 18, and features a somber Kate introducing a new animation created by the Anna Freud Centre as part of the "You're Never Too Young To Talk Mental Health" campaign.

"Mental health is how we feel and think," the Duchess says at the start of the video, which was recorded during a visit to the centre. "Things that can't really be seen, but that affect us every day and talking about them can feel difficult."

"It [the animation] helps us all talk about our mental health"”what to say, and who to talk to when we have feelings that are too big to manage on our own, and how to listen and help if one of our friends is finding things difficult," she continued. "Sometimes, it's just a simple conversation that can make things better."

You can watch Kate's introduction in the video below:

Here's the short animation:

The film and accompanying teaching materials have been circulated to all elementary schools to help children learn how to talk about their feelings, and listen to friends who need to talk.

We will most likely be seeing more of Kate addressing mental health leading up to World Mental Health Day next month.
