ATHENS — Greece’s decade-long economic crisis has taken a heavy toll: Hundreds of thousands of jobs were lost, incomes were slashed and taxes were raised. Hopes for the future were dashed.

For Anna, 68, the crisis had particularly devastating consequences. Her husband, a retired bus driver, killed himself in a park two years ago at age 66 after a series of pension cuts deepened his despair.

“He kept saying, ‘I’ve worked so many years. What will I have to show for it? How are we going to live?’” said Anna, who asked that her full name not be published to protect her family’s privacy. After two years of therapy, she now volunteers to help others struggling with mental health issues.

Depression and suicide rates rose alarmingly during the Greek debt crisis, health experts and studies say, as the country’s creditors imposed strict austerity measures that cut wages, increased taxes and undermined the ability of health services to respond to a crisis within a crisis.
