Depression is a mental disorder caused by many different factors. It was discovered by Hippocrates, a greek physician. He discovered depression by realizing there was an imbalance of four body fluids called humors: yellow bile, black bile, phlegm, and blood. Depression can be caused anywhere from genetic vulnerability, severe life stressors, certain medications, or even the abuse of drugs and alcohol. Studies show that the main reasons of depression usually come from being in a abusive relationship, family issues, and sometimes work stress such as unemployment. Medical conditions can also be a reason why someone may be depressed. Signs of depression are sometimes not easy to see. Depression is more than sadness. The signs in behavior caused by depression can include not going out or enjoying things you use to anymore, distancing from close friends and family, inability to concentrate, not getting anything done at work or school, and relying on drugs and alcohol.
