Three fathers who raised nearly £1m in memory of the daughters they lost to suicide will meet the government next month in the next step of their campaign to get suicide prevention added to the school curriculum.
Tim Owen from Norfolk, Mike Palmer from Greater Manchester and Andy Airey from Cumbria won widespread support last year during a 300-mile trek under the banner of Three Dads Walking.
Now their campaign to get mental health taken more seriously in schools is going to Westminster where they will meet health minister Gillian Keegan.
Mr Owen, from Shouldham near King's Lynn, said society must do more to tackle a mental health crisis - one where thousands of young people are left waiting for treatment, and four schoolchildren take their own lives every week.
He said the Three Dads Walking were determined to see change.
"There's so many different emotions because ultimately I've failed my daughter. She's killed herself," he said.
"I've let that happen. But equally we're doing something to create something positive out of such devastation.
"The three of us would like to see suicide prevention put into schools' PHSE syllabus. We feel that if we can train our young people when they're 11, 12, 13 years old that yes, we all go through down times but suicide is not the answer."
The fathers walked between their homes in 2021 in memory of Emily, who was 19, and 17-year-old Beth Palmer, who both died in March 2020, and Sophie Airey who died just before Christmas in 2018 at the age of 29.
Mr Owen said when Emily took her own life it left a gaping void in his family.
"To start with every day was survival. Getting out of bed, making your own bed in the morning, was survival," he told ITV News Anglia.
"But you've got a decision really. You stay devastated for the rest of your life or you try and do something positive."
At the start the dads hoped to raise a few thousand pounds for suicide prevention charity Papyrus.
Today, their total stands at £857,000.
The Three Dads Walking attracted national attention as they made their way across the country in October last year, finally crossing the finish line in Mr Owen's home village of Shouldham to applause from crowds.
Along the way they were joined for parts of the walk by other people whose lives had been touched by suicide, having conversations with the aim of breaking the taboo around the subject.
