As a continuing drive to raise awareness of mental health issues, today marks World Mental Health Day (WMHD), the annual campaign designed for people to open up a dialogue for sufferers.

Set up in 1992 by the World Federation for Mental Health, WMHD marks each year with a different theme and this year's is suicide prevention.

For this year’s (October 10) WMHD, organisers are asking people for just "40 seconds of action to raise awareness of the scale of suicide around the world and the role that each of us can play to help prevent it" with the Duke of Sussex, Prince Harry and world renowned, and respected, musical superstar, Ed Sheeran joining forces to produce a very special mental health video for the annual campaign designed to raise awareness of mental health issues.

According to the World Health Organisation, the day "provides an opportunity for stakeholders working on mental health issues to talk about their work, and what more needs to be done to make mental health care a reality for people worldwide".

According to the WHO, more than 800,000 people die by suicide each year, and our "actions must be geared towards prevention".

Set up in 1992 by the World Federation for Mental Health, each year is marked with a different theme - this year's is suicide prevention.

President of the WFMH, Dr Alberto Trimboli, says that suicide prevention was chosen this year because it is the leading cause of death among people aged fifteen to 29.

He said: "It has increased gradually in all parts of the world and, in the past few decades, has reached alarming statistical levels.

"It is often believed that it is only adults who exhibit suicidal behaviours, but it should be made known that many children and young people engage in this kind of behaviour as a result of violence, sexual abuse, bullying and cyberbullying.

"Suicide is a global public health problem that deserves the attention of all the actors in the field of mental health."

The aim this year is to call on governments around the world to make tackling suicide a priority.
