Generalised Anxiety Disorder (GAD): Symptoms, Treatment

Generalised anxiety disorder (GAD) is a common mental health condition where a person might very often feel very anxious about lots of different things. It's not the kind of worry that comes and goes with a particular event; it's a constant state of anxiety that can settle in the background of everyday life and rarely lifts.

It can make life difficult to navigate, as anything can be a trigger. Going outside, seeing people, work phone calls, a lot of things that many people wouldn't even think about, can be very hard for someone experiencing GAD. The mind can feel like it's running through worst-case scenarios on a loop, and even when there's nothing obvious to be worried about, the feeling stays.

If you're reading this and wondering why you feel anxious all the time, or you're trying to make sense of what's going on for someone you love, you're in the right place.

What is GAD?

The GAD meaning is fairly straightforward when you break it down. Generalised anxiety disorder is a long-term anxiety condition characterised by excessive worrying about a wide range of situations and issues, rather than one specific thing. It's the "generalised" part that sets it apart from other anxiety disorders; the worry isn't tied to one trigger, it spreads across many areas of life.

People with GAD often describe feeling on edge all the time, even on days when nothing particularly stressful is happening. The worrying becomes chronic, and many describe it as feeling like they can't switch off.

What are the main symptoms of generalised anxiety disorder?

GAD looks different for everyone, but there are some common generalised anxiety disorder symptoms that tend to appear together. The symptoms of GAD can be both mental and physical, and they often build on each other over time.

Common signs include:

• Constantly worrying about everyday things, even minor ones

• Feeling restless, on edge, or unable to relax

• Difficulty concentrating or finding that your mind goes blank

• Irritability that feels out of character

• Trouble sleeping, whether falling asleep or staying asleep

• Feeling tired all the time, even after rest

• A sense of dread that doesn't seem to have a cause

• Going over conversations or decisions repeatedly in your head

• Avoiding situations because of how anxious they might make you feel

The GAD physical symptoms are often what bring people to seek help, because they can be hard to ignore. These can include muscle tension (especially in the jaw, neck, and shoulders), headaches, a racing heart, stomach issues, sweating, dizziness, and shortness of breath. Many people first visit their GP thinking something is physically wrong, only to find that chronic anxiety symptoms have been the cause all along.

What does normal anxiety look like in comparison to GAD?

Anxiety itself is a perfectly normal human response. We all experience it, and in many situations, it can be useful. It's the feeling that helps us prepare, focus, and respond to challenges.

You might feel anxious when:

• Starting a new job

• Giving a presentation at work

• Going on a first date

• Sitting an exam

• Waiting for medical results

• Moving to a new city

• Having a difficult conversation with someone

In all of these examples, the anxiety has a clear cause and a natural endpoint. Once the presentation is over, once the new job starts feeling familiar, once the results come back, the anxiety eases. Your nervous system settles, and life carries on.

Generalised anxiety disorder is persistent in a way that normal anxiety isn't. It doesn't switch off when the situation passes, because it isn't really attached to one situation. Someone with GAD might wake up feeling anxious before they've even thought about the day ahead. They might finish one worry only for another to take its place. Even when life is going well, the anxiety lingers.

This is what makes chronic anxiety disorder so exhausting. It's not the worry itself that wears people down so much as the relentlessness of it. Feeling anxious every day, week after week, month after month, takes a real toll on energy, mood, relationships, and physical health.

If you've been asking yourself why do I feel anxious all the time, and the answer isn't clear, that constant feeling may be something to take a closer look at.

When to seek help

There's no perfect threshold for when to reach out, but a good guide is this: if your anxiety has lasted for six months or more, if it's affecting your daily life, your work, your relationships, or your sleep, or if it feels like it's getting worse rather than better, it's worth speaking to someone.

You don't need to be at crisis point to ask for help. In fact, the earlier you get support, the easier it tends to be to manage. Many people with GAD have lived with it for years before realising what it is, often because the constant anxiety feeling becomes so familiar that it starts to feel like just part of who they are. It isn't. It's a condition, and it responds well to treatment.

Some questions that might help you decide whether to seek help:

• Do I feel on edge most days?

• Am I avoiding things I used to enjoy because of anxiety?

• Is my sleep being affected?

• Have people close to me commented on how anxious I seem?

If you're nodding along to a few of these, a conversation with a GP or a therapist could be a really helpful next step.

GAD diagnosis and treatment

A GAD diagnosis is usually made by a GP or a mental health professional. They'll ask about your symptoms, how long you've been experiencing them, and how much they're affecting your life. There's no blood test or scan for GAD, the diagnosis is based on conversation and clinical judgement.

When it comes to generalised anxiety disorder treatment, there are two main routes that often work well together: therapy and medication.

Therapy is one of the most effective treatments for GAD. Cognitive behavioural therapy (CBT) is widely used and has strong evidence behind it, helping people identify the thought patterns that fuel their worry and develop practical tools to interrupt them. 

Other approaches like psychodynamic therapy can be incredibly helpful too, particularly for people who want to understand the deeper roots of their anxiety, where it comes from, and what it might be trying to communicate. The right approach often depends on the person, which is why working with a therapist who can tailor things to you matters so much.

Medication is another option, and for many people it's an important part of getting well. Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed for GAD, and other types of medication may also be considered depending on your situation. 

Medication is usually prescribed by a GP or a psychiatrist, and it can be especially useful for people whose symptoms are severe enough that therapy alone feels too difficult to engage with. There's no shame in taking medication for anxiety, and for many people it works well alongside therapy rather than as an alternative to it.

What causes GAD isn't fully understood, but research points to a mix of factors. Genetics, brain chemistry, life experiences (particularly stress or trauma), and personality all seem to play a role. Most people with GAD don't have one clear cause, it's usually a combination, which is part of why a personalised approach to treatment works best.

Symptoms in children and teenagers

If you have a child or teenager who appears to be anxious a lot, they may be experiencing GAD. Children and young people don't always have the words to describe what they're feeling, so the signs can look different from those in adults. Here are some signs to look out for:

• Frequent stomach aches, headaches, or unexplained physical complaints

• Difficulty sleeping or wanting to sleep in your bed

• Excessive worrying about school, friendships, or family

• Asking for reassurance over and over again

• Avoiding school or after-school activities they used to enjoy

• Becoming clingy, tearful, or irritable

• Perfectionism or being very hard on themselves

• Constantly worrying about things that haven't happened yet

And here's what you can do to help. Try to take their worries seriously, even if they seem small from where you're standing. To them, those worries are real and heavy. Avoid telling them not to worry, instead, listen and help them think through what might happen and how they could cope. 

Keep routines as steady as you can, because predictability is grounding when anxiety is high. And if it feels like it's affecting their daily life, please don't hesitate to seek professional support, either through your GP or directly through a therapy service that works with young people.

A short note if you're a teenager reading this yourself: what you're feeling is real, and it isn't your fault. It's something a lot of people go through, and there's help available. Talking to a parent, a school counsellor, or your GP is a really good first step.

There is always help 

The important thing to remember is there is always help and always support. Living with permanent anxiety, feeling constantly anxious, going through every day with that knot in your chest, it's not something you have to carry on your own.

Whether you've been feeling like this for years or it's something more recent, reaching out is a brave first step. And it's one you don't have to take alone.
