Depression can be difficult to diagnose because it presents differently in each person. Depression treatment should be tailored to the individual person based ontheir symptoms. In order to determine the depression treatment that is right for you, it is important to understand how depression impacts your daily life. When you think of depression you think of sadness, right? Unfortunately for many patients the first symptom is not sadness. It can take a person a while before they identify they are depressed. Some of my patients notice that they are irritable, eat less, and struggle with insomnia before they start to feel depressed and sad. Other patients sleep more, eat more, and stop enjoying the pleasure of life for several days or even weeks before they begin to feel depressed. Depression has many faces and can also be a normal emotion. Understanding the difference between the emotion and the illness is quite important and often difficult to determine without the help of a psychiatrist or psychiatric PA.
