Anxiety vs Depression: How to Tell the Difference

Anxiety and depression are often discussed as though they are opposites, but they share significant symptom overlap and frequently occur together. Understanding which is dominant, or whether both are present, is one of the most important steps toward getting the kind of support that will actually help.

At their most fundamental, anxiety and depression represent different relationships with uncertainty and the future. Anxiety is characterised by a heightened sense of threat: the future feels dangerous, uncertain or unmanageable, and the nervous system responds with activation, hypervigilance and avoidance. Depression is characterised by a dampening of motivation and positive emotion: the future feels hopeless, meaningless or not worth engaging with, and the nervous system responds with withdrawal, fatigue and disengagement.

Both involve suffering and impairment. But the nature of the suffering is different. Anxiety tends to feel urgent, activated and overwhelming. Depression tends to feel heavy, flat and exhausting. These differences have implications for what helps.

• Sleep problems: anxiety typically causes difficulty falling asleep due to a racing mind, while depression more often causes early morning waking or sleeping excessively
• Concentration difficulties: both anxiety and depression impair concentration, though for different reasons
• Fatigue: the physiological cost of chronic anxiety produces fatigue, and depression produces fatigue through a different mechanism involving motivation and energy regulation
• Social withdrawal: anxiety drives withdrawal through avoidance of situations that feel threatening, depression drives withdrawal through loss of interest and motivation
• Irritability: present in both, particularly in men and younger people where it may be more prominent than sadness

Signs that anxiety is dominant

• The primary experience is worry, dread or fear rather than sadness or emptiness
• You feel activated, tense and on edge rather than flat and drained
• There are specific things you are avoiding because of fear rather than because of disinterest
• The future feels threatening and dangerous rather than pointless
• You can still experience enjoyment when you are not in an anxious state

• The primary experience is sadness, emptiness or numbness rather than worry or fear
• Loss of interest in things that used to matter to you, including things you used to enjoy
• The future feels hopeless or not worth engaging with rather than threatening
• Low energy and motivation that is persistent rather than situational
• Negative thoughts about yourself, your worth and your future that feel like facts rather than fears

Anxiety and depression co-occur very frequently. Studies consistently show that around 50% of people with one have the other at clinically significant levels. When both are present, the pattern is often one of anxiety driving avoidance that leads to depression through isolation and loss of engagement, or depression reducing the emotional resources needed to manage anxiety effectively.

If both are present, it is important to identify which is more dominant as the primary treatment target because some interventions that are effective for anxiety, like exposure, can be harder to implement when significant depression is also present. The anxiety or depression test gives you separate scores for both and identifies which pattern is dominant.
