Most people recognise the sharp spike of nerves before a job interview, a difficult conversation, or a medical appointment. That feeling passes. But for a growing number of people in the UK, anxiety is a constant background noise that colours every part of daily life.
Anxiety disorders present in many ways, and the subtler signs are often the ones that go unrecognised for the longest. Generalised Anxiety Disorder (GAD) is now one of the most prevalent mental health conditions in England, affecting approximately one in twelve adults. The proportion of people meeting GAD criteria has roughly doubled since the early 1990s from 4.4% to 8.5% between 1993 and 2023–24.1 Yet many people living with anxiety remain undiagnosed, unsupported, and unsure whether what they are experiencing counts as a real problem.
If you’ve found yourself searching “do I have anxiety” or wondering how to know if you have anxiety rather than ordinary stress, this article is written for you.
Key Takeaways
- Anxiety becomes a disorder when it is persistent, disproportionate, and disrupts daily functioning.
- Physical symptoms, racing heart, muscle tension, and dizziness are just as real as the psychological ones.
- Avoiding people, places, or decisions to sidestep anxiety is one of the clearest behavioural warning signs.
- A formal anxiety assessment rules out other causes, confirms a diagnosis, and opens the door to the right treatment.
- You do not need a GP referral to access a private anxiety assessment in the UK; you can self-refer directly

What Is Anxiety, and When Does It Become a Disorder?
Anxiety is a normal human response, a built-in alarm system that sharpens attention and prepares the body to respond to a perceived threat. It becomes a disorder when it is excessive, persistent, difficult to control, and begins to interfere with everyday functioning.
According to NHS England, a GP will generally consider a diagnosis of GAD if anxiety has been present on most days for at least six months, is causing significant distress, and is proving difficult to manage. ²˒³  The symptoms can be psychological, physical, or behavioural, and frequently all three at once.
Psychological Signs of Anxiety
These are the thoughts and feelings most closely associated with anxiety, though they are not always named as such by the person experiencing them.
- Constant, uncontrollable worrying: thoughts that cycle without resolution, moving from one concern to the next even when nothing is objectively wrong.
- Difficulty concentrating: a mind that feels restless or scattered, frequently described as “brain fog” or an inability to focus, even on tasks you care about.
- Anticipatory dread: spending significant time imagining what might go wrong before events or conversations.
- Irritability and low frustration tolerance: a shortened fuse that feels out of proportion to the situation.
- A persistent sense of being overwhelmed: feeling that ordinary demands are impossible to manage.
Physical Signs of Anxiety
Anxiety is not purely a mental experience. The body’s stress response produces real, measurable physical symptoms, and many people seek help for the physical signs long before they connect them to anxiety.
- Racing heart or palpitations: a noticeably fast or irregular heartbeat, often triggered by anxious thoughts rather than physical exertion.
- Muscle tension and headaches: chronic tightness in the neck, shoulders, or jaw, and frequent tension headaches. NICE guidelines identify muscle tension as a core associated symptom of GAD.4
- Gastrointestinal symptoms: stomach pain, nausea, or irritable bowel-type symptoms that worsen under stress and improve when worry reduces.
- Fatigue: persistent tiredness that is not explained by poor sleep alone.
- Dizziness and breathlessness: feeling lightheaded or short of breath, particularly in anticipation of anxiety-provoking situations.
- Sleep disruption: difficulty falling asleep, staying asleep, or waking early with thoughts already racing.
Behavioural Signs of Anxiety
The way anxiety changes how a person behaves is often the most disruptive dimension and the most informative sign that something needs attention.
- Avoidance: steering clear of situations, people, or decisions that provoke anxiety.
- Reassurance-seeking: repeatedly checking in with others, revisiting plans, or researching health symptoms online for confirmation that everything is fine.
- Procrastination driven by fear: delaying decisions or tasks not because of laziness but because the thought of making a mistake produces intense anxiety.
- Social withdrawal: reducing contact with friends and family because social interactions feel effortful, unpredictable, or emotionally exhausting.
When It’s Time to Get a Formal Anxiety Assessment
Everyday worry is specific, time-limited, and proportionate. It responds to facts. Anxiety is broad, persistent, and disproportionate; it continues even when circumstances are neutral or positive. A formal assessment is worth seeking if any of the following apply:
- Day-to-day functioning: work, study, relationships, and sleep are consistently affected.
- You are using alcohol, cannabis, or other substances to manage your anxiety.
- You are experiencing low mood or depression alongside your anxiety.
A clinical assessment rules out other possible causes of your symptoms, like thyroid disorders and certain cardiovascular conditions, which can mimic anxiety. It also uses validated tools such as the GAD-7 questionnaire, which measures symptom severity across seven domains and is widely used in both NHS and private settings to support diagnosis and track progress.5

Frequently Asked Questions
What are the most common signs of anxiety disorder in the UK?
The most commonly reported signs include persistent, uncontrollable worry, restlessness, difficulty concentrating, fatigue, muscle tension, sleep disruption, and a tendency to avoid situations or decisions that feel threatening. Physical symptoms such as palpitations, stomach complaints, and dizziness are equally common but frequently attributed to other causes.
How do I know if I have anxiety or am just stressed?
Stress is typically a response to an identifiable external pressure and eases when that pressure resolves. Anxiety tends to be broader, more persistent, and harder to connect to a single cause. If your worry has continued for six months or more, is difficult to control, and is affecting your ability to function day to day, it is worth considering a formal clinical assessment.
Can I get an anxiety assessment online in the UK?
Yes. Private services such as Therachange offer online anxiety assessments with qualified UK clinicians, accessible without a GP referral and typically available far more quickly than NHS routes. These assessments follow the same validated clinical frameworks used in NHS settings, including standardised tools like the GAD-7.
Do I need a GP referral to be assessed for anxiety?
Not necessarily. NHS Talking Therapies allows adults aged 18 and over to self-refer without a GP appointment. For a private assessment, no referral is required at all; you can book directly with a clinical service such as Therachange.
What happens after an anxiety assessment?
Following a formal assessment, a clinician will discuss their findings with you and recommend an appropriate treatment pathway. This might include Cognitive Behavioural Therapy (CBT), other evidence-based talking therapies, a self-help programme, medication prescribed via a GP, or a combination of approaches. NICE guidelines recommend CBT as the primary treatment for GAD in adults.
Are anxiety and depression connected?
Yes. Anxiety and depression frequently occur together. NHS England notes it is common to have more than one anxiety-related condition at the same time, and NICE guidance specifies that when both are present, the more severe condition is typically treated first. If your anxiety is accompanied by persistent low mood, loss of interest, or hopelessness, a comprehensive assessment that covers both is important.
