Sometimes depression is first recognized by friends or family members. If you're having symptoms of depression, be sure to tell your doctor. Don't assume he or she will be able to tell that you are depressed just by looking at you. Your doctor will ask you questions about your symptoms, your health and your family's history of health problems. He or she may also give you an exam and do some tests. It is also important to tell your doctor about any medicines that you are taking.
