Depression symptoms can occur over a period of time, or in some cases, suddenly. This condition is experienced in a variety of ways. Some people may still be productive, but find that they have less energy, enthusiasm, or concentration; while others find it difficult to perform their daily activities or take care of themselves. Treatments for depression range from taking medications to psychotherapy, or include some combination of both. Psychotherapy helps the individual understand and process experiences, emotions, and behaviors, enabling them to cope with this difficult state. There is hope.
