Young women are among the loneliest and most isolated group of people in Australia, according to a study that found four in five felt left out and lacking companionship.

A Headspace survey released on Thursday on the eve of International Women's Day, found young women suffered loneliness more than their male counterparts, even though young men were less likely to ask for help.
