The suicide awareness and prevention organisation, SOSAD, has announced that it will be downgrading its services over what it said is a lack of sustainable funding.
SOSAD, which stands for Save Our Sons and Daughters, also provides a range of mental health and bereavement support services.
The organisation has announced its messaging service will cease from Tuesday as "current circumstances" will not allow for it to be maintained.
However, SOSAD's 24/7 freephone helpline will remain open and the organisation will also continue to offer free counselling services.
Its offices are predominantly located in the north east of the country, with six offices based in counties Cavan, Louth, Laois, Meath and Monaghan.
In a post on social media, SOSAD said it is "devastated" to announced the closure of its messaging service.
"This is a decision we never wanted to make, but with the lack of sustainable funding, difficult choices have had to be made to ensure we can continue providing the support we can," it said.
The organisation described the service as "crucial to so many", adding "its loss is truly heartbreaking".
However, SOSAD said is "fighting every day" to keep the organisation open.
"If you are able, please consider donating to us, every contribution helps us to continue supporting those who need it most," the post concluded.
Concerns about the future of SOSAD have been raised in recent weeks with calls being made to the HSE to allocate emergency funding to allow the suicide prevention service to continue operating into the future.
Since 2007, SOSAD has offered support and services for people who are experiencing suicidal ideation, depression, bereavement, stress and anxiety disorders.
Last year, SOSAD said it delivered 21,402 hours of free counselling, up more than 20% on the figure for 2023.
SOSAD’s messaging support service, which is due to end, operated daily from 8pm to 12am.
During these times, a person could send a message via the organisation’s website to a volunteer after which the individual could then be given a referral to one of SOSAD’s offices for extra support, if needed.
The SOSAD website also states that all of its volunteers have undergone training in crisis interventions and work at a person’s own pace to provide support.
SOSAD’s 24/7 freephone helpline, which will still remain fully operational, can be contacted on 1800 901 909.
