(Salem, OR)  --  A recent study says Oregon has the worst mental illness rate in America.  The non-profit Mental Health America ranked Oregon dead last among the other 49 states and the District of Columbia for mental illness rates and little access for help with it.  The study shows Oregon has some of the worst rates for homelessness, high school graduations and child abuse, all of which contribute to mental illness.  A new outpatient center is opening later this month in northeast Portland, but experts say even more are necessary.
