When you think about someone who is depressed, you may picture someone who looks very sad all the time. While a sad mood is a symptom of depression, depressed people do not always look sad. Instead, some people who are depressed seem to have lost interest in all or almost all activities that they use to find enjoyable. In addition to these mood changes, depressed people may show a variety of physical symptoms.
Most depressed persons have trouble falling asleep and staying asleep.
They may find that they are waking up earlier than they normally do, day after day, and are unable to fall back to sleep. A lack of energy is also a common symptom, to the point that the depressed person may not have the energy to carry out their normal daily tasks. For example, they may not have the energy they need to get themselves out of bed in the morning. Changes in appetite are also common. Most find they lose their appetites, while others experience an increase in appetite.
