Depression is a common mental disorder that varies in severity. While early or mild depression often manifests as sadness, irritability, anger, and persistent fatigue, the condition can progress if not managed and treated promptly. Severe depression presents more serious symptoms that significantly impact an individual's quality of life.

One of the most alarming signs of severe depression is a profound loss of interest. Individuals often no longer experience joy in life, losing enthusiasm for activities they once cherished. This symptom is linked to neurotransmitter imbalances in the brain, particularly dopamine, which plays a role in generating feelings of interest and satisfaction.

Accompanying this loss of interest are intense feelings of despair. Severe depression plunges individuals into a state of hopelessness and prolonged despondency, significantly increasing the risk of suicide. Patients frequently lack motivation for treatment, tend to neglect work and social relationships, and often harbor negative thoughts about their future.

In severe stages, the ability to perform basic self-care activities diminishes. Individuals may lose the motivation to carry out daily tasks such as eating, bathing, working, or caring for their family, highlighting a significant functional impairment.

Difficulty sleeping is another pervasive symptom. People with depression often struggle to sleep due to anxiety, restlessness, and unstable moods, making it hard to fall asleep or causing frequent awakenings. Many also tend to stay in bed, withdrawing to avoid confronting negative emotions, which disrupts their circadian rhythm. Depression is also frequently accompanied by sleep disorders like chronic insomnia, restless sleep, or even excessive sleeping, all of which diminish sleep quality and overall health.

Irritability, annoyance, or anger are common manifestations of depression, particularly as the condition worsens. This symptom is often linked to emotional dysregulation, prolonged stress, or co-occurring anxiety. Persistent irritability can negatively affect studies, work, and social relationships.

Less common but possible in severe depression is psychosis. Patients may experience hallucinations, such as hearing or seeing things that are not real, and delusions, involving thoughts or beliefs that deviate from reality.

Individuals with depression, whether mild or severe, may also experience other physical symptoms. These include headaches, abdominal pain, light sensitivity, constipation, and unusual weight changes. Some may also speak slowly or have difficulty expressing their thoughts.

It is crucial for families to show concern, talk, and share when they notice unusual symptoms in a loved one. Early examination is vital for patients to receive timely diagnosis and treatment, preventing the condition from worsening.
