Ireland has less than half of the mental health rehabilitation teams it needs, with none in Donegal, Wicklow or North Tipperary.
While teenagers say their mental health is the biggest issue they face.
13 years ago the Government laid out their mental health policy.
One of the recommendations was to set up 48 mental health rehabilitation teams around the country, consisting of a psychologist, a nurse and specialist.
But just 23 are in place - with none in Donegal, Wicklow or North Tipperary.
The Mental Health Commission says even in Galway where there is a service its poorly staffed, while in Mayo, the team is only available to people living in Castlebar.
According to UNICEF 97 per cent of young people say mental health is the biggest concern among their peer group.
The survey revealed that following education and employment, 23 per cent were stressed about climate change, while 2 percent cited Brexit as a concern
