Quick answer
If you're asking "am I anxious or stressed?", the biggest clues are what's causing the feeling and how long it lasts. Stress is usually a response to an outside cause, such as a tight deadline, and it typically subsides once the situation is resolved. Anxiety is an internal response that can continue even without a clear trigger, often as excessive worrying that is difficult to control.
Stress and anxiety side by side
Stress and anxiety can feel very alike. Both can leave you tense, tired and short-tempered. The differences are easier to see when you compare them directly.
| Stress | Anxiety | |
|---|---|---|
| Where it comes from | Usually an outside cause, such as a deadline at work or an argument with a friend | An internal response that can persist without a clear external trigger |
| What happens over time | Typically subsides once the situation is resolved | Worry can be excessive and hard to control |
| Common signs | Difficulty sleeping, trouble concentrating, feeling overwhelmed, headaches or an upset stomach | Restlessness, a sense of dread, difficulty concentrating, feeling constantly worried or fearful |
| Everyday impact | Often tied to the pressure you're under | May affect daily life even when there is no identifiable problem |
Notice the overlap. Trouble concentrating appears in both lists, so a single symptom rarely settles the question. The pattern matters more: what set it off, and whether it fades when the pressure does.
If you'd like a private starting point while you think this through, Mindhelpa offers a free and private mental health screening. It is not a diagnosis. It is a way to put some of what you're feeling into words.
Work, money and sleep: three everyday examples
These are made-up examples to show how the pattern might look. Your own experience may be different.
Work
Imagine you have a big presentation on Friday. All week you feel on edge, you snap at colleagues and your shoulders ache. On Friday afternoon it's over, and within a few days you start to feel more like yourself. That fits the pattern of stress: a response to an external cause that typically subsides once the situation is resolved.
Now imagine the presentation went well, but you still feel dread on Sunday evenings and keep replaying conversations, with no particular problem to point to. That is closer to the way anxiety can continue even in the absence of a clear external trigger.
If work pressure has been building for months rather than days, it's also worth reading about burnout symptoms at work in the UK, because long-running work strain is a different question from a single busy week.
Money
A surprise bill or a tight month can make anyone worry. Stress is a normal reaction to challenging situations, including recurring ones at work or with money. The Royal College of Psychiatrists adds that if feelings continue after the initial problem passes, it may be anxiety.
The NHS makes a similar point: feeling worried about money, relationships or work is common, but persistent and uncontrollable worries that interfere with daily life could be a sign of an anxiety disorder. So the question isn't whether you worry about money. It's whether the worry stays in charge after the problem has been dealt with.
Sleep
Sleep is a good place to look because both stress and anxiety can disturb it. According to Mind, stress-related sleep problems often improve when the stressful situation resolves, while anxiety might keep affecting sleep despite efforts to address worries.
So if you've sorted the thing that was keeping you awake and you're still lying there with a busy mind, that's a useful detail to notice and write down.
Questions to ask yourself
Mind suggests self-reflection questions can help you tell the two apart, such as: is my worry tied to a specific situation, or does it persist regardless of what's happening?
Here is a short list to work through. Grab a pen if that helps, and answer honestly rather than quickly.
- Can I name the situation that's causing this feeling?
- If that situation ended tomorrow, would I expect to feel better?
- Has the feeling eased in the past when a problem was solved?
- Do I worry even when nothing is going wrong?
- Do I find the worry hard to switch off, even when I try?
- Am I feeling restless, fearful or a sense of dread without knowing why?
- Is my sleep still disturbed after the stressful thing has passed?
- Is this getting in the way of work, relationships or things I normally enjoy?
There is no score to add up. If most of your answers point to a clear cause that is fading, stress may be the better fit. If most point to worry that has no clear cause, or that stays after the problem has gone, it may be worth looking more closely at anxiety. Neither result is a diagnosis, and only you and a health professional can work out what's really going on.

What you can do next
You don't need to have it all worked out before you do something about it. A few gentle steps:
- Write down what you notice. Jot down when the feeling shows up, what was happening, and how long it lasted. Patterns are easier to spot on paper.
- Note your sleep. Record whether sleep trouble follows a particular worry or happens regardless.
- Try a free and private screening. Mindhelpa's free and private mental health screening is not a diagnosis, but it can help you see which areas of your life to think about. If you're curious about what comes afterwards, read what happens after a mental health screening.
- Speak to your GP. If worry is hard to control or is affecting your daily life, your GP is the right person to talk to about support options. Your pharmacist can also answer questions about managing everyday symptoms.
Mindhelpa's free anxiety screening covers similar areas to the GAD-7, a widely used anxiety questionnaire, but it is not the GAD-7 and is not scored as one. It is not a diagnosis.

Frequently asked questions
Can stress and anxiety feel the same?
Yes, they can look very similar. Trouble concentrating is listed as a sign of stress and also as a symptom of anxiety. That's why it helps to look at the cause and how long the feeling lasts, not just one symptom.
Is it normal to worry about money or work?
Yes. Worry about money, relationships or work is common. The NHS says that when worries are persistent, feel uncontrollable and interfere with daily life, they could be a sign of an anxiety disorder, so that is the point to talk to your GP.
Can an online screening tell me if I have anxiety?
No. A screening is not a diagnosis. Mindhelpa's free anxiety screening covers similar areas to the GAD-7, a widely used anxiety questionnaire, but it is not the GAD-7 and is not scored as one. It is not a diagnosis. You can use it as a free and private first step and take what you learn to your GP if you want to talk it through.
What if my worry isn't going away?
Feelings that continue after the original problem has passed may be a sign of anxiety. Speak to your GP, and bring any notes you've made about when the worry happens. If you ever feel unsafe, use the urgent help details above.
