Understanding Anxiety: From Normal Worry to Anxiety Disorders
Anxiety is a natural human response to perceived threat — a survival mechanism honed over millennia. The problem arises when this alarm system becomes oversensitive, firing in response to situations that are not genuinely dangerous, or persisting far beyond what is helpful. That is when anxiety becomes an anxiety disorder.
When Does Anxiety Become a Disorder?
Anxiety becomes a clinical disorder when it is: excessive (disproportionate to the actual threat), persistent (lasting weeks or months rather than resolving once the stressor passes), and impairing (significantly affecting work, relationships or daily functioning). If you can identify with these three criteria for most days in the past 6 months, it is worth seeking an assessment.
Types of Anxiety Disorders
Generalised Anxiety Disorder (GAD): Persistent, excessive worry about multiple areas of life — work, health, finances, relationships — that is difficult to control.
Social Anxiety Disorder: Intense fear of social situations where you might be judged, embarrassed or rejected. Often leads to avoidance of social events, public speaking and meeting new people.
Panic Disorder: Recurrent unexpected panic attacks (sudden surges of intense fear with physical symptoms) and persistent worry about future attacks.
Specific Phobias: Intense, irrational fear of specific objects or situations (heights, flying, injections, specific animals).
Physical Symptoms of Anxiety
Rapid heartbeat, shortness of breath, chest tightness, muscle tension, sweating, trembling, nausea, dizziness, and fatigue. These symptoms occur because the anxiety response triggers the sympathetic nervous system ("fight or flight"), flooding the body with adrenaline and cortisol.
Cognitive Symptoms
Catastrophic thinking ("the worst will definitely happen"), mind reading ("they must think badly of me"), overestimation of threat, difficulty concentrating, mental blanking, and hypervigilance to potential threats.
Effective Treatments
CBT is the most evidence-based treatment, teaching you to identify and challenge anxious thought patterns and gradually face feared situations. Mindfulness-Based Cognitive Therapy (MBCT) is also effective, especially for preventing relapse. Medication (SSRIs, SNRIs) is used for moderate to severe anxiety, often alongside therapy.
