TV star Bressie, who suffered crippling panic attacks in his teenage years, told TDs that families are driving "hundreds of miles" to access a mental healthcare professional.
The judge on RTÉ's 'The Voice', whose real name is Niall Breslin, appeared at the Oireachtas Health Committee yesterday.
He told politicians they must "accept that our mental health services and systems are not even close to being adequate or resourced for the demand and requirement that is put upon them".
"This is not a blame game or headhunt, but in order for us to build an effective long-term strategy we have to park the egos, politics and economics and put human beings first.
"I have heard horror stories regarding the child and adolescent mental health services that are almost too distressing to share on this platform.
"Families totally abandoned, while some families have to drive hundreds of miles and wait months to see a healthcare professional.
"We have got to address preventative measures that can allow people deal with their mental health issues at an infancy stage and also educate others in recognising how the mind works," he added.
