Former Dublin GAA star Shane Carthy is raising concerns about people's mental health over what is set to be a very different Christmas period.
The GAA player has been very open about his own battle with anxiety and depression and is now an ambassador for Pieta House.
"I've been to the deepest and darkest places anyone could imagine with suicidal ideations never leaving my side," Carthy said.
"Thankfully, through the help of the GPA, St Patrick's Mental hospital, family and friends, I've risen from these depths and began to see the light.
"I'm joining Pieta in their quest to illuminate the path for others who may find themselves in similar difficulties."
This year, Pieta's Christmas campaign is called #HopeOverSilence. The appeal is asking people to light a candle and place it in their window at 7pm tomorrow.
As many people may find themselves alone and struggling this festive season, the national suicide prevention charity is appealing to people to open up and break the stigma surrounding loneliness.
Instead of a moment's silence, the charity is calling for everyone to reach out to someone they love, to make a phone call, talk to a family member or join the social media #HopeOverSilence conversation.
A spokesperson for Pieta House said: "With dark nights can come dark thoughts and particularly at this time of year, it can pose a real challenge to our mental health so supporting friends, family members and colleagues is important.
"People are naturally social. They like conversation and they like to feel supported and to be part of a community, but if you are feeling low, it can be harder to seek out that support and connection."
Singer Mary Black is also encouraging people to help break the stigma surrounding loneliness.
"We know that Christmas will be different this year, but we can still ensure we stay connected and speak up, to ensure hope - over silence," she said.
