Suffering or not suffering from these illnesses doesn't have anything to do with a person's will power. Many times, society assumes a person suffering from depression is just lazy or lacks motivation to get their life together. One might be labeled as simply having a behavior problem. This simply is not true. Many drugs used in treatment of other illnesses such as cancer, heart disease, high blood pressure or arthritis as well as oral contraceptives and some antibiotics can trigger depressive illnesses.
Depression is the most common, most misdiagnosed illness in America.
