Donal Walsh, the teenager from Co Kerry who lost his battle to cancer in May 2013, was again trending on Twitter. A host of Irish celebrities took to the social networking site following the airing of RTE documentary 'Donal Walsh – My Story.'

The programme looks at the life of the anti-suicide campaigner, who passed away aged 16 earlier this year after a four-year battle with cancer.

The production was broadcast on RTE Two and the Twitter reaction was incredible. #DonalWalsh was still trending across Ireland on Thursday morning as people continued to log on to pay tribute to the brave young man.

Donal was fondly remembered for his empowering message before his death. He urged the Youth of Ireland to think twice about suicide and to ask for help. Life was precious to this young man and he wanted to spread this message.

Donal's mother Elma took to Twitter to encourage the public to spread the late Donal’s message
"Come on we need to get this trending and known all over Ireland." She added, "He'll want to see this from Heaven."

Broadcaster Miriam O’Callaghan tweeted her congratulations to the team behind the documentary. She described Donal as "truly inspirational."

The documentary saw contributions from Munster and Ireland rugby player Paul O'Connell, Kerry GAA star Paul Galvin and singer Niall Breslin.

O'Connell spoke of how he had become "firm friends" with Donal and said he had been inspired by him, while Paul Galvin said he thought Donal would have "made a great sportsman."
