By CommPRO Editorial StaffThe U.S. is one of the most depressed countries in the world, according to media expert and author Michael Levine (www.MichaelLevineMedia.com).  In terms of quality years of life lost due to disability or death – a widely adopted public health metric that measures the overall burden of disease – the U.S. ranked third for unipolar depressive disorders, just after India and China. India, China and the U.S. are also the countries most affected by anxiety, schizophrenia and bipolar disorder, said Levine.  "About one in five adults in the U.S. experiences some form of mental illness each year, according to the National Alliance on Mental Illness, but only 41 percent of those affected received mental health care or services in the past year," Levine reported.
