Millions of people in the UK who care for sick, elderly or disabled friends or relatives are missing out on life chances because of a lack of support from those around them.
More than 6.5 million people voluntarily look after a loved one, according to charity Carers UK.
But a lack of understanding about their role means many see their own health decline or are forced to give up work or cut their hours.
Jo Vidler, whose daughter Livvy has hypoadrenalism, told ITV News that it could be a real challenge to balance employed work with being a carer, but that having both was important.
"It can be a real challenge trying to juggle to two," she said.

In a study of more than 6,000 carers half had let a health problem go untreated or seen their mental health get worse.
Fewer than a third said they got they help they need when there is an emergency, while just under half said they had struggled financially.
Emily Holzhausen, director of policy at Carers UK, said it was essential there was better support for carers.
"We're calling on individuals, organisations and governments to think about what they can do to improve the lives of carers in their community," she said.
The survey's findings come ahead of Carers Week, which is run by seven charities to celebrate and recognise the work carried out by millions of carers across the UK.
