Kate Middleton and Prince William are continuing their campaign for mental health awareness.

Sitting in front of photos of their three children, the royal couple recorded a video message thanking everyone who has been part of the U.K. organization Time to Change's campaign to end stigmas concerning mental wellbeing.

"We wanted to say a big thank you to everyone who has shared their experiences and taken action through Time to Change, helping to challenge the stigma which surrounds mental health," William, 38, said.

"Movements like Time to Change have helped to transform attitudes and encouraged more openness about mental health in schools, communities and the workplace," added Kate, 39.

William praised the organization's influence in making mental health awareness part of the "mainstream," but Kate added a warning: The "work isn't done yet."

"We need to keep talking, keep taking action and continue to stand up to the stigma," William said.

The message comes ahead of Time to Change's closure in England on March 31, when its funding ends.

The video message comes just weeks after Prince Harry and Meghan Markle's revealing interview with Oprah Winfrey, where they spoke about their struggles within the royal family and why they stepped back from their senior roles. Meghan even shared that she struggled with suicidal thoughts during her time in the royal family.

"I was ashamed to say it at the time and ashamed to have to admit it to Harry. But I knew that if I didn't say it — then I would do it," the 39-year-old mom said. "I just didn't want to be alive anymore."
