Depression affects millions of people each year. There are some 21 symptoms of depression; only one of the symptoms is sadness. Depression can also incude changes in sleep, appetite, sex drive (libido), as well as loss of attention, concentration and memory. Things which used to be fun or pleasurable no longer are. There can be increased irritability, sensitivity to criticism, and a general sense that things will never get better. Suicidal thoughts and behaviors can be part of the picture as well. The type of treatment for depression depends upon its type and severity. It may include cognitive behavior therapy (CBT), insight-oriented therapy, psychodynamic therapy, and often we work with qualified physicians who provide medication for the treatment of depression.
