Grief or Loss can be triggered by various events:

• Death of a loved one
• Death of a pet
• Break up of a relationship
• Divorce
• Job change
• Move

Grief can lead to symptoms of depression such as:

A persistent sad, anxious or "empty" mood
Sleeping too little or sleeping too much
Reduced appetite and weight loss or increased appetite and weight gain
Loss of interest or pleasure in activities once enjoyed
Restlessness or irritability
Persistent physical symptoms that don't respond to treatment (such as headaches, chronic pain, or constipation and other digestive disorders)
Difficulty concentrating, remembering, or making decisions
Fatigue or loss of energy
Feeling guilty, hopeless or worthless
Thoughts of death or suicide

If you experience five or more of these symptoms for longer than two weeks or if the symptoms are severe enough to interfere with your daily routine, you should see your doctor or a qualified mental health professional.
