The following are some major symptoms of depression (from the DSM IV a diagnostic manual). They serve as building blocks for the diagnosing the disorder.

1. Depressed mood most of the day, nearly every day, as indicated by either subjective report (e.g., feels sad or empty) or observation made by others (e.g., appears tearful). Note: In children and adolescents, can be irritable mood.

2. Markedly diminished interest or pleasure in all, or almost all, activities most of the day, nearly every day (as indicated by either subjective account or observation made by others).

3. Significant weight loss when not dieting or weight gain (e.g., a change of more than 5% of body weight in a month), or decrease or increase in appetite nearly every day. Note: In children, consider failure to make expected weight gains.

4. Insomnia or hypersomnia nearly every day.

5. Psychomotor agitation or retardation nearly every day (observable by others, not merely subjective feelings of restlessness or being slowed down)

6. Fatigue or loss of energy nearly every day.

7. Feelings of worthlessness or excessive or inappropriate guilt (which may be delusional) nearly every day (not merely self-reproach or guilt about being sick).

8. Diminished ability to think or concentrate, or indecisiveness, nearly every day (either by subjective account or as observed by others).

9. Recurrent thoughts of death (not just fear of dying), recurrent suicidal ideation without a specific plan, or a suicide attempt or a specific plan for committing suicide.

   Feeling depressed in some situations is completely normal and reasonable, especially when traumas or losses occur. If depression has continued for more than a few months, or if it is identified as a long standing pattern, it may indicate something of a more chronic nature. In either case, there are new, non-addictive medications that can be extremely helpful in balancing emotions and improving mood. They are specifically designed to have subtle effects in desireable ways. It is important to use these resources when appropriate to aid emotional well-being.
