Quick answer
Yes — anxiety can cause or contribute to low mood. The exhaustion, life limitation, and demoralization of living with anxiety can lower mood, and anxiety and depression are closely linked. Addressing the anxiety often lifts the associated low mood — and both are very treatable.
How anxiety lowers mood
Anxiety can genuinely cause or contribute to low mood through several routes. Living with anxiety is exhausting — the constant worry, physical tension, and disrupted sleep drain your energy and emotional reserves, which naturally dampens mood. Anxiety also causes avoidance and life limitation: as you steer around anxiety-provoking situations, you may withdraw from activities, relationships, and opportunities that would normally bring pleasure and connection, and losing these sources of positivity lowers mood. And the ongoing struggle and frustration of dealing with anxiety can be demoralizing. So while anxiety is primarily about fear and worry, its downstream effects often include low mood.
The anxiety-depression link
This connection reflects the broader, close relationship between anxiety and depression. The two frequently co-occur and feed each other, sharing underlying vulnerabilities and often triggered by the same things. Persistent anxiety can wear a person down toward low mood and, if untreated, contribute to developing depression over time. So low mood alongside anxiety is common and understandable — it can range from mild, anxiety-related dampening of mood to more significant depression accompanying the anxiety. Recognizing that your low mood may be connected to your anxiety helps make sense of it and points toward addressing both together.
What helps
The encouraging part is that addressing the anxiety often lifts the associated low mood — as you reduce the anxiety, re-engage with life, and improve sleep and energy, mood frequently improves too. Treatment approaches help both: CBT addresses the anxious thinking and the withdrawal that lowers mood (including behavioral activation to re-engage with rewarding activities), and lifestyle measures like exercise, sleep, and connection benefit both anxiety and mood. If the low mood is significant or persistent, treating it directly (and considering whether it's become depression) matters too. A note of care: if you have thoughts of harming yourself, please reach out for support right away. If anxiety is dragging your mood down, please know it's common and very treatable — reaching out for help can lift both the anxiety and the low mood.
