Last year, more than 6,000 people took their own lives in the UK and Republic of Ireland.
Men are three times more likely to take their own lives compared to woman, and suicide remains the biggest killer of men under 45 in the UK.
Sophie Airey, a nurse working in Edinburgh, was twenty nine when she died last year. She took her own life, just before Christmas. She loved outdoor activities, and had given her family no indication she had any suicidal thoughts.
Her father Andy, from just outside Penrith, is now helping the suicide prevention charity Papyrus. It says that suicide is the biggest killer of young people under 35 in the UK.
