The primary symptom of PGD is intense grief that lasts for more than a year. This grief is often accompanied by other symptoms, such as difficulty sleeping, loss of appetite, and suicidal thoughts.

The average duration of PGD is more than 3 years. However, some people may experience symptoms for a shorter or longer period of time.

Increased energy is not a symptom of PGD. In fact, people with PGD often experience fatigue and difficulty sleeping.

All of the above are risk factors for developing PGD. People who have a history of trauma, a family history of mental illness, or who experience the sudden or unexpected death of a loved one are more likely to develop PGD.

PGD is diagnosed based on a psychiatric evaluation. During the evaluation, the psychiatrist will ask about the person's symptoms, medical history, and family history. The psychiatrist may also order blood tests or a physical examination to rule out other medical conditions.

There is no one-size-fits-all treatment for PGD. Treatment may include medication, therapy, support groups, or a combination of these approaches.

Antidepressants are commonly used to treat PGD. These medications can help to improve mood and reduce symptoms of depression and anxiety.

All of the above types of therapy are commonly used to treat PGD. These therapies can help people to learn how to cope with their grief and develop healthier coping mechanisms.

Support groups for PGD are typically led by a trained therapist and provide a safe space for people to share their experiences and learn from each other. Support groups can help people to feel less alone and develop a sense of community.

Most people with PGD recover within a few years. However, some people may experience symptoms for a longer period of time.
