Prince William On Impact Of Mental Health Campaign: 'Lot To Process'

Prince William has opened up about the impact of his and wife Kate Middleton's campaign for mental health.

On Friday, Prince William visited the Data Observatory at Imperial College London to find out how much the Heads Together campaign, an initiative spearheaded by him, Middleton and Prince Harry, have made an impact on the public. "I feel like it's exam results day," the Duke of Cambridge said upon his arrival.

Prince William, Middleton and Prince Harry are proud advocates of mental health. In fact, the trio has given $2.7 million to a new digital initiative that aims to help improve people's mental health. They have also been open about their own personal struggles and encouraged the public to "smash the stigma" about mental health concerns. And when he saw the figures generated by their campaign on Friday, Prince William said it was "amazing" and added that there was a "lot to process," People reported.

Prince William, Middleton and Prince Harry set up the Royal Foundation with the hopes of spreading information to help more people with mental health issues and give them practical solutions, aside from simply encouraging them to talk about their struggles.

As part of their campaign, the trio is expected to celebrate the contributions of those who are working in the mental health sector across the UK next week. The Duchess of Cambridge, along with her husband and Prince Harry, will be hosting a reception at Kensington Palace for World Mental Health on Tuesday.

The upcoming event will be Middleton's first public appearance since her third pregnancy was confirmed. The preparations will not be difficult for the mom-of-two as her new righthand woman, Catherine Quinn, is already hard at work on it.

Middleton has been suffering from hyperemesis gravidarum or severe morning sickness. Her condition has prevented her from attending various royal engagements. Due to the illness, she also missed her son Prince George's first day of school. Fortunately, the duchess' condition seems to be improving as her family is convinced that worst of the illness is already behind them.

"[Middleton] has such a rotten time during this early month," a source told E! News. "But she's out of the woods now and doing well."
