According to the Institute of Mental Health, one in every four adults over the age of 18 suffers from a diagnosable mental disorder ... that’s almost 50 million people. Depression and anxiety are the number one cause of disability in America, and research shows that almost every one of us will struggle with at least a short-term metal illness during our life. If you don’t struggle with a mental disorder you most likely have a loved one who does. Not one of us is unaffected.
