We all feel anxious sometimes. It's natural. That alert, tense attentiveness is a survival tactic, after all, meant to keep us vigilant to the dangers around us. But for 12% of Canadians, anxiety becomes an everyday thing. Anxiety can become persistent and without purpose, with distressing physical and emotional symptoms that disrupt daily life.

Of all mental illnesses, anxiety disorders are the most common. The following are the main types:

Generalized anxiety disorder (GAD)
Living days marred by nearly-constant and exaggerated worries, people with generalized anxiety disorder just can't seem to shake that "bad" feeling. Money, relationships, health problems, career and job issues, what to wear, what will happen - you name it, when you have GAD almost anything can trigger excessive worrying and associated physical symptoms.

GAD can interfere with sleep and make it hard to ever just relax. Anxiety symptoms range from fatigue and irritability to headaches, muscles aches, nausea, and panic-like trembling and twitching. A diagnosis of generalized anxiety disorder usually happens if a person has worried excessively more days than not for at least 6 months. Click here to learn more about generalized anxiety disorder.

Panic disorder
Panic attacks are at the pounding, rapidly beating heart of panic disorder. Anyone can be gripped by sudden panic attack symptoms, including increased heart rate, dizziness or light-headedness, sweating, or shortness of breath. Other panic attack symptoms include a feeling of unreality or a fear of suddenly losing control or dying. A person with panic disorder has more frequent panic attacks that can happen at any time and without warning - or in particular anxiety-inducing situations.

The fear that a panic attack might occur can lead to avoidance of normal activities. Some people with panic disorder become afraid to leave their residence, a more extreme anxiety disorder called agoraphobia. Click here to learn more about panic disorder.

Social anxiety disorder
Social anxiety disorder, also known as social phobia, stems from fears involving other people. People with social anxiety disorder are disproportionately self-conscious and may fear being watched, negatively judged, or publicly embarrassed in some way. A person with social anxiety may be focused on one particular social-based fear or worry, like eating in front of others, or they may be anxious in general about many different types of social interactions.

If a person with social phobia is faced with their anxiety triggers, the symptoms are similar to those of general anxiety - blushing, sweating, trembling, and nausea. People may also experience panic attacks, triggered exclusively by social situations. Worries about social situations can lead to avoidance of social situations and can make it difficult to even interact with co-workers, friends or classmates, leading to fewer relationships.
