Anxiety and Depression

What are Anxiety and Depression?

Anxiety disorders and depressive disorders are distinct but frequently co-occurring mental health conditions that can rise to the level of disability when they significantly impair daily functioning.

Anxiety disorders include:

• Generalised Anxiety Disorder (GAD) — persistent, excessive worry about multiple areas of life
• Panic Disorder — recurrent, unexpected panic attacks with anticipatory anxiety
• Social Anxiety Disorder — intense fear of social situations due to fear of scrutiny or embarrassment
• Specific Phobias
• PTSD — while classified separately, often presents alongside anxiety

Depressive disorders include:

• Major Depressive Disorder (MDD) — persistent low mood, anhedonia, fatigue, and functional impairment lasting at least two weeks
• Persistent Depressive Disorder (Dysthymia) — lower-level but chronic depression lasting at least two years
• Seasonal Affective Disorder (SAD)

Both anxiety and depression have biological (neurochemical, genetic), psychological, and environmental causes. They are not character flaws, signs of weakness, or choices. They are as real as any physical condition.

Disability Status

Under the Americans with Disabilities Act (ADA), anxiety disorders and depressive disorders qualify as disabilities when they substantially limit one or more major life activities. This includes limitations in:

• Thinking and concentrating
• Communicating
• Working
• Sleeping
• Interacting with others

Many people with severe anxiety or depression qualify for reasonable accommodations in workplaces and educational settings — yet are often met with scepticism because mental health conditions are invisible.

How It Presents

Anxiety can present as:

• Persistent worry and rumination that is difficult to control
• Physical symptoms: racing heart, shortness of breath, muscle tension, sweating
• Avoidance of situations that trigger anxiety (which can severely restrict life)
• Difficulty sleeping, concentrating, making decisions

Depression can present as:

• Persistent low mood or emptiness
• Loss of interest or pleasure in activities (anhedonia)
• Fatigue and low energy
• Changes in sleep (too much or too little) and appetite
• Difficulty concentrating and making decisions
• Feelings of worthlessness or excessive guilt
• In severe cases, suicidal thoughts

Both conditions can be episodic — people may function well for periods and then experience significant deterioration.

Assistive Technology and Supports

AT in mental health is a growing field:

• Mental health apps — mood tracking, CBT-based tools (MoodKit, Woebot), mindfulness (Headspace, Calm)
• Crisis support tools — apps and text lines that provide immediate support
• Scheduling and reminder systems — for people whose executive function is impaired during depressive episodes
• Noise-cancelling headphones — for managing sensory overload in anxiety
• Accessible workplaces — remote work options, flexible scheduling, and reduced sensory environments as accommodations
• Telehealth — therapy and psychiatric appointments by video, reducing access barriers

Common Misconceptions

• "Anxiety and depression are not real disabilities." Severe anxiety and depression can be as functionally limiting as physical conditions, and are legally recognised as disabilities.
• "Just exercise/think positive and you'll be fine." While lifestyle factors can support wellbeing, severe anxiety and depression often require professional treatment — therapy, medication, or both.
• "People with depression are just sad." Depression is a complex neurobiological condition involving changes in mood, energy, cognition, and physical function.

Language and Identity

Person-first language is most common in clinical contexts ("person with depression"). Many people, however, use identity-adjacent language informally ("I have anxiety," "I'm a depressive") as part of destigmatising their experience. The psychiatric survivor and Mad Pride movements advocate for rights-based, non-pathologising approaches to mental health.
