Americans are among the most stressed people in the world, according to a new survey. And that’s just the start of it.

Last year, Americans reported feeling stress, anger and worry at the highest levels in a decade, according to the survey, part of an annual Gallup poll of more than 150,000 people around the world, released on Thursday.

“What really stood out for the U.S. is the increase in the negative experiences,” said Julie Ray, Gallup’s managing editor for world news. “This was kind of a surprise to us when we saw the numbers head in this direction.”

For the annual poll, started in 2005, Gallup asks individuals about whether they have experienced a handful of positive or negative feelings the day before being interviewed. The data on Americans is based on responses from more than 1,000 adults.
