Depression
Depression can lead to dysania. The relationship between these two conditions is significant because depression can make sleeping difficult for you and the lack of sleep can exacerbate the symptoms of depression. In some cases, fatigue caused by other medical conditions like CFS/ME can result in depression. With the right approach and treatment method, depression can be completely treated. You can talk to your healthcare professional to create a treatment plan for you.
Grief
Grief can be caused by different factors, including the loss of someone. People react to loss in different manners. In some cases, you may experience some emotional effects like anger, anxiety, guilt, and deep sadness immediately. Physical consequences such as sleep troubles, disruption of the immune system, and heart problems are also common. When grief persists for a long time, it is known as prolonged or complicated grief.
