Depression and anxiety are two of the most common mental health problems worldwide. According to the World Health Organisation (WHO), over 300 million people suffer from depression, and over 260 million people suffer from anxiety.

Both conditions can significantly impact a person’s daily life, leading to difficulties in relationships, work/school performance, and overall quality of life.

Depression

Depression is a mood disorder characterised by persistent sadness, hopelessness, loss of interest or pleasure in activities, and a lack of energy.

It is not a sign of weakness or a character flaw, but rather a mental illness that affects millions of people worldwide.

Early Warning Signs of Depression

Feeling sad or “empty” most of the day, every day
Loss of interest or pleasure in activities you once enjoyed
Significant weight loss or gain without dieting or exercise
Difficulty sleeping or sleeping too much
Feeling restless or agitated
Feeling tired or lacking energy every day
Feelings of worthlessness or guilt
Difficulty concentrating or making decisions
Recurrent thoughts of death or suicide
Physical symptoms such as headaches or stomachaches that do not have a physical cause

Causes of Depression

Depression is caused by a combination of genetic, environmental, and psychological factors. People with a family history of the condition are more likely to develop it themselves.

Stressful life events, such as trauma, abuse, or a major life change, can trigger depression in susceptible individuals. Neurotransmitter imbalances, such as a deficiency in serotonin or dopamine, can also contribute to depression.

Anxiety

Anxiety is an emotional state characterised by worry, fear, and nervousness. It is a normal human response to stress or danger, but for people with an anxiety disorder, these feelings are persistent and can be debilitating.

Early Warning Signs of Anxiety

Excessive worry or fear about everyday situations
Being easily startled or frightened
Feeling restless, irritable or “on edge”
Feeling tired or lacking energy every day
Difficulty concentrating or making decisions
Physical symptoms such as sweating, trembling or heart palpitations
Difficulty sleeping or sleeping too much
Feeling like your mind is “racing”
Avoiding situations that trigger anxiety
Recurrent and intrusive thoughts about danger or catastrophic events

Causes of Anxiety

Anxiety can be caused by a variety of factors, including genetics, brain chemistry, and environmental stressors. People with a family history of anxiety disorders are more likely to develop it themselves.

Neurotransmitter imbalances, such as low levels of GABA or high levels of norepinephrine, can also contribute to anxiety. Environmental factors, such as trauma, abuse, or a major life change, can trigger anxiety in susceptible individuals.

Treatment Options

Both depression and anxiety are treatable conditions.

The most effective treatment for mild to moderate depression and anxiety is a combination of psychotherapy, such as cognitive-behavioural therapy (CBT), and medication, such as selective serotonin reuptake inhibitors (SSRIs). For severe cases, electroconvulsive therapy (ECT) or transcranial magnetic stimulation (TMS) may be necessary.

Self-Help Strategies for Anxiety and Depression

There are several self-help strategies that can help alleviate symptoms of depression and anxiety. These include:.

Regular exercise
Healthy diet
Good sleep hygiene
Stress management techniques such as meditation or deep breathing exercises
Positive social interactions, including spending time with friends and family
Pursuing hobbies or activities you enjoy
