Hadar Swersky says that as people age, sometimes changes take place that may cause us to experience stress and sadness. The transition from work to retirement, the death of a dear one, or the analysis of an illness, can all make us feel uneasy, anxious, and unhappy and contribute to depression over time. Certain symptoms of depression are:

• feeling sad, unhappy, or empty
• loss of interest in normal activities
• changes in appetite
• anxiety or restlessness
• feeling worthless or guilty
• irrational reactions or angry outbursts
• difficulty sleeping, insomnia, or sleeping too much
• difficulty concentrating or making decisions
• unexplained pain
• thoughts of suicide or death
