2. The sense of hopelessness, long-term pessimism, seeing no prospects in one`s life, negative attitude to most things, etc.

3. Lacks of self-appraisal, helplessness are some other standard signs of a depressive condition. These symptoms cause in a patient a feeling that he does not deserve happiness and unable to enjoy life. Helplessness adds to intensification of the depressive condition. Such patients always have a sense that everything goes wrong and this is another symptom of depression.

4. Lack of interest in feeling or search of pleasure. The things that used to cause enjoyment are no longer of interest. These symptoms show how a person can change under the influence of this disease.

5. Indifference, apathy, constant tiredness. Patients experience mental sufferings from everything happening to them, especially after they have lost interest in life and no longer have the physical energy they used to have before that. They also suffer from loss of appetite and sleeplessness which also have a bad effect on their physical health.

6. Depression worsens memory and concentration which may interfere with the ability to interact with the world around. Since a depressed person is busy with himself only, he is unable to keep track of things happening in the outer world and is unable to remember what other people told or what was happening around him. Lack of interest in the world around makes him very inattentive.

Of course, there are much more symptoms which could warn about depression and that it is time to see a doctor. Lack of sleep or sleepiness, regular awakenings due to urges to urinate at night- these are all symptoms of depression. Overeating and lack of appetite also signal about lack of love of life. Sudden weight loss or, on the contrary, weight gain, suicidal thoughts, frequent talks about death are also symptoms of depression. In the result of these deviations physical disorders may occur, e.g. stomach disorder, headache, etc.
