Need treatment for depression?

Nowadays the number of people affected by depression is increasing.
Sorrows, job's reasons, any sort of stress may have a negative impact on frail individuals. Fortunately, there are several methods to contrast depression. Looking for info on the net I've found that there are basically two kinds of treatment: psychotherapy and medication.

Psychological treatment (psychotherapy) assists the depressed individual in several ways. First of all, it helps ease the pain of depression and addresses the feelings of hopelessness that accompany depression.  Secondly, it changes the pessimistic ideas, unrealistic expectations, and critical self-evaluations that create depression.

Cognitive therapy helps the depressed person recognize which life problems are critical and which are minor. It also helps the individual to develop positive life goals and a more positive self-assessment. Thirdly, problem solving therapy changes the areas of the person's life that create significant stress and contribute to depression.

Unfortunately, the therapy alone will not eliminate the depression. Supportive counseling is helpful as part of the overall treatment plan. But, unless the depressed person makes critical life changes, the depression will continue. These changes are both internal and external. Internal changes include problem assessment, self-evaluation, the evaluation of others and the expectations the depressed person has. External changes include problem solving skills, stress management, communication skills, life management skills and the skills to develop and sustain relationships.

What the length of the treatment is concerned, I've read that it varies according to the severity of the depression and the number and kind of life problems that need to be addressed. Most people will begin to experience some relief with 6 to 10 sessions, and approximately 70-80% of those treated notice significant improvement within 20-30 sessions. Treatment sessions are usually scheduled once per week, although they may be scheduled more frequently initially, or if the person is experiencing significant life crises.
