Almost Half are Mentally Ill?

We found this story on two different Chinese pages, but we couldn't find corroboration from any other source (including WaPo, but our Internet connection is not fully functional right now, so our searching was limited). You may want to hesitate before accepting it as fully truthful. Link. Excerpt:

The United States leads in mental illness globally with 46 percent of Americans suffering mental disorders ranging from anxiety, depression to substance abuse in their lifetime, The Washington Post reported Tuesday.

Within the past year, about 25 percent of all Americans met the criteria for having a mental illness, and fully 25 percent of those had a "serious" disorder that significantly disrupted their ability to function day to day, according to a one-year-and-a-half survey of the country's mental health, conducted by the University of Michigan.

The 46 percent seems halfway believable, if they're including everyone who's gone through a crisis or has engaged in binge drinking (ridiculously defined as five or more drinks in a sitting). We're more surprised by the 25 percent figure.
