Psychology is the study of human behavior and the human mind. There are psychology quotes which deal with a variety of mental functions and processes. Someone who practices psychology is called a psychologist, and usually these professionals can not prescribe prescription medications. A psychologist discusses the problems that a person is having and then helps by offering advice and providing feedback. If someone with a serious mental illness visits a psychologist they are generally referred to a psychiatrist or other qualified individual for any drugs or other treatment types that are needed to address the severe mental illness. Many people around the world visit a psychologist for many different reasons, and some may just need someone to talk to and vent with so that they get relief from the daily stress that we all experience. If you have been through a traumatic experience then psychology may help you work through this.
