Businesses and organisations of every hue are suffering - or will soon suffer - from the fallout of the Covid-19 outbreak, and that includes the country's charities.

Some have been forced to cancel or reschedule major fundraising campaigns in order to adhere to social distancing guidelines.

That includes Pieta House, which has moved its Darkness Into Light event from May until some time in the Autumn.

"If you take last year there was about 170,000 people that got up in the middle of the night, put on their yellow t-shirt, they came in and met their friends and families in their communities and they walked across multiple venues right over Ireland, and raised a phenomenal €5.4m for Pieta," said Elaine Austin, CEO of Pieta House. 

"Their funds and their generosity of the people that come out and support Darkness into Light really enables Pieta to deliver its services. We are 80% funded by the public and Darkness into Light is a huge, huge part of that funding."

That made the decision to postpone the event a major one for the charity - however it was ultimately deemed best to do so in interest of the health and safety of the local organisers as well as the participants. 

It will instead take place in the autumn, and Ms Austin is confident that people will show their support when that eventually comes around.

"The support for Darkness into Light is really there and it's so fantastic," she said. "We're really confident we'll have that support again in the autumn and I'd imagine that by the time we get to it that people will be so delighted to come out into their communities.

"Going through this period is just so difficult. Human beings are social!"

But in the mean time the change has created a funding gap for Pieta, which is now calling on the public to help it maintain its services in the coming months.

During that time those services will also likely face an increase in communication from the public, as the isolation created by social distancing measures takes its toll on people's mental health.

Increased anxiety about the Covid-19 outbreak is also likely to impact too.

"There's a definite increase in the level of anxiety and people feeling stressed, and it's palpable," said Ms Austin. "We've seen that come through on the website, the helpline and the text.

"So it's really important during this time of need that we make sure, as much as we possibly can, that nobody feels alone and there's always someone to listen, someone to talk to and someone to help."

Pieta House is also advising people to take certain steps to try to minimise the impact that increased isolation and anxiety is having on their own health.

That includes limiting the amount of information they consume about the virus - with people urged to strike the balance between staying informed and being overwhelmed.

Ms Austin also encourages people to try to remain as active as they can, even in the difficult situation they find themselves, and work hard to keep their sleep routine and eating habits as 'normal' as possible.

She says people should also use whatever technology is available to them to stay in contact with people while also respecting the official guidance.

"From our perspective the most important thing is staying connected to others - it's really important that nobody feels alone," she said. "Use the video calls, the telephone calls - and also use the online supports.

"If you feel that you need to talk to someone, lift the phone. It's really, really important."
