Tom McEvoy of Pieta House, says listening support is there for anyone who's struggling with their mental health:
In the best way possible. Describe how you feel that you're very low perhaps that you are seeing no future, maybe, reaching out for that help can save a life can save your life. Maybe you know that 1800 247247 number your furniture is a lifeline, it's a crisis helpline people are on the other end of that line, who aren't able to help you, so we can really help somebody who is struggling, and in a dark place.
