The ‘LiveLife’ video was produced by the HSE’s National Office for Suicide Prevention with the support of his family.
In the video which was recorded at his home in Tralee, Donal spoke of how he would talk to his parents or friends when he was feeling low, and encouraged others to do the same.
“I’d say to somebody who’s standing there in a room and they feel there’s no windows and no doors — just black — to take time and a door will open, someone will be at that door.
“You can go to the door as well, anyone can find their own door they just have to ask, and it takes a lot of courage to ask.”
His message, which is aimed at 15-19 year olds, will be shown in schools nationwide in an attempt to prevent teen suicide.
Donal’s parents launched the video on RTÉ’s ‘Saturday Night Show’, where their son first shot to prominence having penned on open letter to the media on the topic of youth suicide.
That television appearance encouraged Minister of State with responsibility for mental health Kathleen Lynch to approach Donal and his family to record his message.
