Depression can be caused by suppressing your feelings and life energy, by repressed anger, or unmourned losses. These processes are often adaptive at the time they were created. Often, in our culture the expression of feelings has been discouraged. Therapy for depression can help you to create a safe environment in which you can move in the direction of feeling and expressing these underlying states so you can become more comfortable with your emotional world. Everyone approaches this process in their own time and pace to come to a more comfortable relationship to their internal world.
