Nearly 40% of disadvantaged young people in Wales believe they do not get enough help to deal with alcohol and drugs issues, new research has claimed.
Prince Charles set up the Prince's Trust in 1976
The Prince's Trust has carried out the survey of the country's 'hardest to reach' 14-25-year-olds.
Nearly half said that, with certain issues, they would not seek support from anybody - not even family, friends or specialist support agencies.
This is most likely to apply to areas such as health, drugs and sexuality.
The trust hopes that, by highlighting the problem faced by young people, politicians and those in power will start to tackle them.
Earlier this year, the trust launched a new strategy to help one million young people it has identified as disadvantaged across the UK.
It aims to get millions of pounds invested in schemes, including apprenticeships, for young people who are not in education or employment.
Elsewhere in Thursday's report, 38% of those questioned in Wales believe they are held back by a lack of qualifications, while 33% suffer from a lack of confidence.
And 40% feel there is not enough advice to deal with monetary problems.
The trust claims there are over 108,000 14-24 year olds in Wales who are "economically inactive", while a further 13,100 are claiming Job Seekers Allowance.
Jane James, director of the Prince's Trust Cymru, said the report showed "that disadvantaged young people in Wales have the same aspirations as their peers, but do not know how to reach these goals".
"In particular they feel that they do not have the opportunity to gain the practical skills and qualifications that they need in order to help them into education, training and employment.
"Organisations across Wales need to work with these young people, listen to what they say, and work with them."
She warned that, if this advice was not taken, young people faced entering "a life-time of disaffection and economic inactivity".
Almost half of young people surveyed say that there is a lack of things to do in their spare time, which leads to boredom and anti-social behaviour.
The trust has said there is a need for these young people to be reached, and to help them develop.
It also calls for more provision of activities in local communities, which could also offer informal learning opportunities.
The Prince's Trust has helped almost half-a-million young people since it was founded by the Prince of Wales in 1976.
