Stress occurs in everyone's lives. Receiving a huge student loan bill, going through a divorce and planning a wedding can be sources of stress. However, not everyone becomes depressed.
Stress Causing Depression

There are physical symptoms for both such as headaches, stomachaches and sleep problems. With depression, the physical symptoms would be magnified.

Extreme sadness, thoughts of suicide and feelings of hopelessness and worthlessness are signs of depression.
