Faced with a restricted social life and added uncertainty at an already precarious moment in their lives, many young people are suffering from a gnawing sense that they are losing precious time in their prime years.

Across the world, they have lost economic opportunities, missed traditional milestones and forfeited relationships at a pivotal time for forming identity.

“Many feel they’re paying the price not of the pandemic, but of the measures taken against the pandemic,” said Dr. Nicolas Franck, the head of a psychiatric network in Lyon, France. In a survey of 30,000 people that he conducted last spring, young people ranked the lowest in psychological well-being, he said.

In Italy and in the Netherlands, some youth psychiatry wards have filled to record capacity.
