Anxiety and depression are two of the most common mental health conditions, and they are often spoken about together. As they can share similar symptoms and frequently occur alongside one another, it can be easy to confuse them or assume they are the same condition. However, while anxiety and depression can overlap, they are distinct conditions with different features and, in some cases, different treatment needs.
This guide explains what anxiety and depression are, how their symptoms can compare, and the key differences between them. It also explores how both conditions may be treated, including newer options such as ketamine therapy for people who have not responded adequately to more conventional care.
What Is Anxiety and Depression?
Anxiety and depression describe two different emotional and physical states. Anxiety is characterised by excessive worry, fear, and a sense of impending threat, often accompanied by physical symptoms such as a racing heart, restlessness, and tension. It tends to be future-focused, centred on what might go wrong.
Depression is characterised by persistent low mood, loss of interest or pleasure, and a sense of hopelessness or emptiness. It tends to be more rooted in the present and past, weighed down by feelings of worthlessness or fatigue.
Both are recognised mental health conditions, both are common, and both are treatable. The difference lies in the underlying emotional drivers and the way symptoms present.
Some symptoms of anxiety include excessive worry, a racing heart and feeling restless or on edge.
Symptoms of Anxiety and Depression
While the two conditions are distinct, their symptoms can overlap considerably, which is part of why they are so often confused with each other.
Common Symptoms of Anxiety
- Excessive or uncontrollable worry
- Feeling restless, on edge, or unable to relax
- A racing heart, sweating, or trembling
- Difficulty concentrating because the mind feels overwhelmed
- Trouble sleeping, often due to a racing mind
- Avoiding situations that trigger fear
- A constant sense of dread or anticipation
Common Symptoms of Depression
- Persistent low mood or sadness
- Loss of interest in activities once enjoyed
- Fatigue and low energy
- Feelings of worthlessness or guilt
- Changes in appetite and sleep, either too much or too little
- Difficulty concentrating or making decisions
- Thoughts of self-harm or hopelessness in more severe cases
Where They Overlap
Some symptoms can occur in both anxiety and depression, which is why a proper assessment is important. For example, sleep difficulties, poor concentration, irritability, fatigue and restlessness can all appear in either condition.
The difference often comes down to what sits beneath those symptoms. Anxiety is usually shaped by fear, worry or a sense of threat, while depression is more closely linked to persistent low mood, hopelessness or a loss of interest in things that once mattered.
While anxiety largely revolves around fear and anticipation, depression is more closely linked to low mood and a loss of interest.
What Is the Difference Between Anxiety and Depression?
The table below illustrates some of the differences between anxiety and depression:
| Area of difference | Anxiety | Depression |
|---|---|---|
| Focus | Fear, worry and anticipation | Low mood, loss and disconnection |
| Thinking pattern | Often focused on what could go wrong or what might happen next | Often focused on hopelessness, guilt, worthlessness or a lack of meaning |
| How it tends to feel | Often feels like the mind and body are on high alert with racing thoughts | Feeling low, flat, unmotivated or emotionally drained |
Anxiety is largely about fear and anticipation. The mind is often racing, scanning for threats and preoccupied with what could happen next. It tends to keep the body in a heightened state of alertness. Physically, anxiety can also feel activating. Some people experience restlessness, muscle tension, a racing heart, shortness of breath or a sense of being on edge.
Depression, by contrast, is more closely linked to low mood and loss of interest. It can slow a person down, affecting their energy, motivation and ability to feel pleasure. It can affect energy, sleep, appetite, concentration and the ability to take part in daily activities. For some people, depression may also involve feelings of hopelessness, guilt or worthlessness.
Anxiety and depression can also occur together. Many people experience symptoms of both, and the difference between them is not always clear. For example, ongoing anxiety may eventually contribute to low mood, while depression may create worries about the future or fear about being unable to cope.
Can Anxiety Cause Depression?
A common question is whether anxiety can lead to depression. The answer is yes, although the relationship can work both ways. Living with persistent anxiety can be mentally and physically exhausting. Ongoing worry, heightened stress and avoidance of certain situations can gradually wear a person down.
Over time, this may contribute to feelings of hopelessness, low mood and depression. The reverse can also happen. Depression may lead to anxiety through worries about the future, fear of not being able to cope, or distress about the condition itself.
How Are Anxiety and Depression Treated?
Treatment for anxiety and depression often involves similar approaches, especially when both conditions are present. However, the focus of treatment may differ depending on the person’s symptoms, their severity and how each condition is affecting daily life.
For anxiety, treatment often focuses on reducing excessive worry, managing physical symptoms, easing avoidance behaviours and helping the person feel more able to cope with uncertainty.
For depression, treatment is often more focused on improving mood, rebuilding motivation, restoring routine and supporting the person to reconnect with activities, relationships or goals that may have started to feel difficult or meaningless.
Common treatment options may include:
- Talking therapies, such as cognitive behavioural therapy, which can help people recognise and change unhelpful thought patterns and behaviours.
- Medication, including antidepressants such as SSRIs or SNRIs, which may be prescribed for anxiety, depression or both.
- Lifestyle strategies, such as regular exercise, improved sleep, reduced alcohol and caffeine intake, and mindfulness or relaxation techniques.
- Social support, including peer support, family support or structured support networks.
For many people, a combination of therapy, practical lifestyle changes and, where appropriate, medication can lead to meaningful improvement. When standard treatments for depression have provided limited relief, other options may be considered after a careful clinical assessment.
Ketamine as a Treatment for Depression and Anxiety
For people living with treatment-resistant depression or anxiety, ketamine-based treatment may be considered in some circumstances. Unlike traditional antidepressants and anti-anxiety medications, which usually take several weeks to have an effect and primarily act on serotonin or noradrenaline pathways, ketamine works through a different brain pathway involving glutamate. For some people, this may be associated with a more rapid improvement in symptoms.
Ketamine treatment is delivered in a clinical setting and should only take place after a thorough psychiatric assessment. It is not usually considered a first-line treatment and is generally reserved for people who have had limited improvement with more established treatment options. For suitable candidates, ketamine may form part of a broader care plan that includes psychiatric oversight and ongoing monitoring.

FAQs
What is the difference between anxiety and depression?
Anxiety and depression can share some symptoms, but they are different conditions. Anxiety is usually centred on fear, worry and anticipation, often making a person feel tense, restless or unable to switch off. Depression is more closely linked to persistent low mood, loss of interest, reduced motivation and emotional heaviness. While anxiety can feel like the mind and body are on high alert, depression can make everyday tasks feel harder to begin or sustain.
Can anxiety cause depression or vice versa?
Yes, the relationship can work both ways. Ongoing anxiety can be exhausting, especially when constant worry, poor sleep, physical tension or avoidance begins to affect daily life. Over time, this can contribute to low mood, hopelessness and depression. Depression can also lead to anxiety, particularly when someone feels worried about the future, their ability to cope or whether they will feel better again.
Can depression and anxiety occur together?
Yes, anxiety and depression commonly occur together. This is sometimes described as co-occurring or comorbid anxiety and depression. When both are present, a person may feel low, exhausted, or unmotivated, while also feeling tense, restless, or worried. Treatment can often be tailored to address both conditions together.
How are anxiety and depression treated?
Anxiety and depression are often treated with similar approaches, although the focus of treatment may differ. Talking therapies such as cognitive behavioural therapy can help with unhelpful thought patterns, avoidance behaviours and emotional coping. Medication may also be considered where appropriate, alongside lifestyle strategies such as regular movement, improved sleep and reduced alcohol or caffeine intake. Where depression and anxiety have not responded adequately to standard treatments, newer options such as ketamine treatment may be considered after a clinical assessment.
What is worse, anxiety or depression?
Neither anxiety nor depression is automatically worse than the other. Both can significantly affect daily life, relationships, work, sleep and overall well-being. The severity depends on the person’s symptoms, how long they have been present and how much they interfere with everyday functioning. When anxiety and depression occur together, the overall impact can feel more complex, which is why early intervention is vital.
