Having Anxiety and Depression Together: What It Feels Like and What Helps
Anxiety and depression are the two most common mental health conditions and they frequently co-occur. Estimates suggest that up to 60 percent of people with an anxiety disorder will also experience a depressive episode, and vice versa. The combination is not simply the sum of the two: it creates a specific experience that is often more difficult to manage than either condition alone.
Understanding how anxiety and depression interact when they co-occur, what the combined experience looks and feels like, and what treatment approaches are most effective for both simultaneously, is important for anyone navigating this presentation.
Why anxiety and depression occur together so often
Anxiety and depression share biological underpinnings including dysregulation of the serotonin, norepinephrine and HPA axis stress systems. They also share cognitive features, particularly negative bias in the interpretation of information, and are both worsened by sleep disruption, social isolation and physical inactivity.
Anxiety frequently causes depression through a specific pathway: the sustained depletion, avoidance and loss of positive experience that chronic anxiety produces creates the conditions for depression to develop. When anxiety leads to increasing withdrawal from activities, relationships and opportunities, the resulting loss of positive reinforcement and meaning is a direct pathway to depressive symptoms.
Depression also worsens anxiety through reduced cognitive resources for managing worry, reduced motivation to use the skills that manage anxiety and increased negative interpretive bias that makes threats appear more significant.
What the combined experience feels like
The combined experience of anxiety and depression has a distinctive quality that people in this presentation often describe as worse than either alone.
The anxiety provides activation without direction: the urgency, the worry and the physiological arousal of anxiety are present, but the motivational energy of depression means there is no capacity to act on them. The result is a state of agitated paralysis: feeling that something must be done while being unable to do anything.
The depression removes the capacity for pleasure and positive engagement that would normally provide relief from anxiety. The brief respites from anxiety that come from positive experiences, connection, achievement and absorption in activity, are reduced or absent.
The anxiety prevents the rest and withdrawal that depression needs: the activated state of anxiety makes the sleep and restoration that depression requires more difficult to achieve.
How the two conditions maintain each other
In co-occurring anxiety and depression, each condition worsens the other through several mechanisms.
Avoidance, which is driven by anxiety, reduces the behavioural activation and positive reinforcement that are essential for depression recovery. The more the anxiety leads to withdrawal, the more the depression deepens.
The negative cognitive bias of depression, interpreting neutral events as negative and amplifying negative experiences, increases the perception of threat that drives anxiety. The world appears more threatening when depression is present, which generates more anxiety.
Poor sleep, which is a feature of both conditions, reduces the cognitive and emotional resources available for managing either.
What treatment works for both
CBT has strong evidence for both anxiety disorders and depression and is typically the first-line psychological treatment for co-occurring presentations. The cognitive components, addressing negative interpretive bias and catastrophic thinking, are relevant to both. The behavioural components, behavioural activation for depression and exposure for anxiety, target the avoidance that maintains both conditions.
The sequencing of treatment components matters. In presentations where depression is severe, beginning with behavioural activation, increasing engagement with activities that provide positive reinforcement before addressing the anxiety directly, is typically more effective than starting with the anxiety work.
Physical activity has particularly strong evidence for co-occurring anxiety and depression because it addresses both through overlapping mechanisms.
The anxiety or depression quiz on this site helps clarify which pattern is currently more prominent, which is useful for prioritising where to focus first.
Getting support for both
Co-occurring anxiety and depression responds well to treatment but typically requires professional support rather than self-help alone. The complexity of managing two interacting conditions makes the guidance of a skilled therapist more valuable than in single-condition presentations.
If you are experiencing both anxiety and depression, the Do I Need Therapy quiz can help you assess the level of impact and whether professional support is warranted. The anxiety vs depression guide provides detailed information on how the two conditions differ and overlap.
The relationship varies between individuals. In many people, anxiety develops first and depression follows as a consequence of the sustained depletion, avoidance and loss of positive experience that chronic anxiety produces. In others, depression develops first and anxiety follows. In some, both develop simultaneously in response to significant life stressors.
Yes. Chronic anxiety depletes cognitive and emotional resources, produces sleep disruption and drives avoidance of positive experiences. These effects, sustained over time, create the conditions for depression to develop.
Treatment needs to address both conditions, but the components and sequencing may differ from treating either alone. CBT is effective for both. When depression is severe, behavioural activation is typically prioritised before anxiety exposure work. Medication that addresses both, such as SSRIs and SNRIs, is more commonly recommended for co-occurring presentations.
The clearest distinction is the quality of the low mood. Anxiety without depression typically involves urgency and activation alongside the distress. Depression is characterised by loss of motivation, reduced positive affect and a flat or empty quality that is different from the urgent activation of anxiety.
