Which condition is characterized by sleep disturbances and feelings of guilt, often following the loss of a loved one?

Major depressive disorder is a mental health condition that can manifest following significant life events, such as the loss of a loved one. This disorder is characterized by persistent feelings of sadness, loss of interest in previously enjoyed activities, difficulty concentrating, and notable changes in sleep patterns, which include insomnia or hypersomnia. In addition to these symptoms, individuals may also experience feelings of worthlessness or excessive guilt, especially in the context of mourning a loved one.

In this scenario, following the loss of a loved one, it is common for an individual to reflect on their relationship, which can lead to self-blame and guilt. These feelings can exacerbate depressive symptoms, further impairing the individual's ability to cope with the grieving process.

Other conditions like adjustment disorder can occur in response to a significant life change but typically involve symptoms that may elevate in severity when adjusting, rather than the more profound and pervasive feelings of guilt and sleep disturbances associated with major depressive disorder. Generalized anxiety disorder primarily involves chronic anxiety and excessive worry without necessarily the profound sadness and guilt characteristic of depression. Acute stress disorder may involve anxiety and intrusive thoughts following a trauma but typically manifests in a shorter timeframe post-event and may not encompass the same depth of emotional disturbances seen in major depressive disorder.
