The still waters of the Great Salt Lake run deep -- and dark.
Take Wendy, a 40-year-old teacher and mother of three from Utah County. To all appearances, she led the perfect life. Just as she was expected to, she went from high school cheerleader to Mormon missionary to wife and mother.
"But life has a funny way of not being perfect," she said. "Three years into my marriage my husband was drinking, using drugs and stepping out on me.
"I knew I was depressed and needed help, but there is a stigma about depression in this area," said Wendy, who asked that ABCNEWS.com not use her last name. "People think it's a sign of weakness. It means you're not capable of being a good mother or wife or teacher."
Wendy's secret is Utah's secret. The postcard image of Utah is a state of gleaming cities, majestic mountains and persistently smiling people. But new research shows a very different picture of the state, a snapshot of suicide and widespread depression.
A recent study by Mental Health America, the country's oldest independent mental health advocacy organization, ranked Utah the most depressed state in the country.
Another survey released last week by drug distribution company Express Scripts found that residents of Utah were prescribed antidepressant drugs more than those of any other state and at twice the national average.
According to MHA, some 10.14 percent of adults in Utah "experienced a depressive episode in the past year and 14.15 percent experienced serious psychological distress. ... Individuals in Utah reported having on average 3.27 poor mental health days in the past 30 days."
The reason for Utah's mass depression, however, is unknown.
"The truth is, we don't know why," said Dr. Ted Wander, spokesman for the Utah Psychiatric Association.
Neither study was broken down by gender, but nationally women are twice as likely to be diagnosed with depressive disorders as men, experts told ABC News.
Psychiatrists point to several factors that could contribute to Utah's high levels of depression: limited mental health resources, restricted access to treatment as a result of cost, poor quality of resources and a varied list of other factors, including an underfunded educational system and a culture deeply rooted in the Mormon faith.
"Availability to resources, a lack of professionals and barriers to treatment, including the ability to pay all drive up instances of depression," said Dr. Curtis Canning, a Logan-based psychiatrist and former president of the Utah Psychiatric Association. "But there is also -- especially when it comes to women and girls -- a cultural factor."
Seventy percent of Utah's residents are Mormon. When Express Scripts issued its first national survey of prescription drug use in 2002, it sparked a heated debate across Utah about what, if any role, the church played in the state's high dependence on antidepressants such as Prozac and Zoloft.
