Physical symptoms can include:

• Feeling run down
• Not sleeping well
• Change of appetite
• Weight gain or loss
• Physical pain

Emotional Symptoms can include:

• Being easily overwhelmed
• Guilt
• Frustration
• Feeling miserable
• Very Irritable
• Not able to make a decision

Mental symptoms can include:

• Thinking you are worthless
• Believing you are a failure
• Life is not worth living.

If you think you know someone who is experiencing depression then you can help them by taking with them and encouraging them to see a doctor.  There are many checklists available on the internet if you or someone you know believe they may be suffering from depression.
