Generalized Anxiety Disorder Symptoms: When Worry Takes Over

What are the symptoms of generalized anxiety disorder?

The core symptom of generalized anxiety disorder (GAD) is excessive worry that is hard to control, shows up more days than not, and attaches itself to many different areas of life — work, health, money, family, the future. According to the DSM-5-TR, the American Psychiatric Association's diagnostic manual, that worry must persist for at least six months and come with at least three of six accompanying symptoms in adults: restlessness or feeling keyed up, being easily fatigued, difficulty concentrating, irritability, muscle tension, and sleep problems. The worry also has to cause real distress or get in the way of daily life. Reading a list like this can be unsettling, so it is worth saying plainly: only a licensed clinician can diagnose GAD, and matching a few symptoms on a list is not the same as having the condition.

How is GAD worry different from everyday worry?

Everyone worries. Worry before a job interview, during a health scare, or while waiting on a loan decision is a normal response to uncertainty. The difference with GAD is not that the worry exists — it is how the worry behaves.

Everyday worry tends to be proportional to the situation, tied to a specific problem, and it fades when the problem resolves. The worry the DSM-5-TR describes in GAD is different in a few recognizable ways:

• It jumps from topic to topic. The moment one worry settles, another takes its place. People often describe a chain of "what ifs" that never reaches a stopping point.
• It feels out of proportion. A minor email from a boss becomes an afternoon of dread. A child's cough becomes hours of researching rare illnesses.
• It resists control. Telling yourself to stop worrying doesn't work, and distraction only works briefly. The DSM-5-TR specifically names difficulty controlling the worry as part of the picture.
• It persists. Not a rough week or a stressful month, but worry on more days than not for six months or longer.
• It costs something. Lost sleep, strained relationships, avoided decisions, exhaustion at work. The worry isn't just unpleasant — it interferes.

If your worry switches off once the stressful situation passes, that pattern looks more like ordinary stress. If the worry has become the background noise of your life regardless of what is actually happening, that is the pattern worth discussing with a clinician.

What symptoms does the DSM-5-TR actually list?

Because "anxiety" gets used loosely in everyday conversation, it helps to know what the diagnostic manual actually requires. Per the DSM-5-TR, a diagnosis of generalized anxiety disorder involves all of the following:

1. Excessive anxiety and worry, occurring more days than not for at least six months, about a number of events or activities — not just one fear.
2. Difficulty controlling the worry.
3. At least three of these six symptoms (only one is required for children): restlessness or feeling keyed up or on edge; being easily fatigued; difficulty concentrating or the mind going blank; irritability; muscle tension; and sleep disturbance — trouble falling asleep, staying asleep, or restless, unsatisfying sleep.
4. Clinically significant distress or impairment in social, work, or other important areas of functioning.
5. The symptoms are not better explained by a substance, a medication, a medical condition, or another mental health condition.

That last point matters more than people expect. Part of a real evaluation is ruling things out — a clinician will ask about caffeine, medications, medical history, and other conditions whose symptoms can look like anxiety, because treating the wrong thing helps no one.

What does GAD feel like in the body?

Many people are surprised that their first clue wasn't the worry itself — it was the body. Muscle tension is one of the six DSM-5-TR symptoms, and people often carry it in the jaw, neck, and shoulders for so long they stop noticing it until a headache arrives. Others notice stomach trouble, a racing heart, chest tightness, nausea, or dizziness, and some end up in urgent care convinced something is physically wrong.

Those physical experiences are real, and they deserve real attention — both because anxiety can produce them and because other medical causes need to be ruled out first. We cover this in detail in our article on why anxiety can cause chest tightness, nausea, and dizziness, including when a symptom warrants a medical workup before anything else. The short version: new or severe chest pain, trouble breathing, or fainting should always be evaluated medically first. Anxiety is a diagnosis a clinician reaches after other causes are considered, not a label to self-apply to an alarming symptom.

Sleep is the other place GAD often shows itself physically. Lying awake while your mind runs through tomorrow's worries, waking at 3 a.m. with your thoughts already racing, or sleeping a full night and still waking exhausted are all patterns people describe when worry has taken over.

Could it be something other than GAD?

Quite possibly — and this is exactly why an evaluation is worth more than a symptom checklist. Several conditions share symptoms with GAD, and the overlap is genuinely confusing from the inside:

• Depression also causes fatigue, poor concentration, irritability, and sleep problems. Many people experience both at once, and depression treatment looks different from anxiety care in important ways, so sorting out which is driving the picture matters.
• OCD involves intrusive, repetitive thoughts that can feel like worry, but obsessive-compulsive disorder has its own pattern — obsessions paired with compulsions or mental rituals — and responds best to approaches designed for it.
• ADHD shares difficulty concentrating and restlessness. Some people pursue an ADHD evaluation and discover anxiety is the better explanation; for others it is the reverse, and some people have both.
• Trauma-related conditions can produce constant vigilance and a body that never relaxes. If your anxiety traces back to specific frightening experiences, trauma-focused care may be the more accurate fit.

None of this means you should try to diagnose yourself by comparison shopping. It means the question "what is actually going on?" is a clinical one, and a thorough evaluation is designed to answer it.

When should I get an evaluation?

A reasonable rule of thumb: if worry has been interfering with your sleep, your work, your relationships, or your ability to enjoy anything for weeks or months — or if the people who love you have started commenting on it — it is time to talk to someone. You do not need to wait until things are unbearable, and you do not need to be certain it's "bad enough." Figuring out whether it meets a diagnostic threshold is the clinician's job, not yours.

An evaluation with a psychiatric provider typically involves a detailed conversation about your symptoms, their history, your medical background, and what you've already tried. From there, you and your provider can discuss options together; our page on anxiety treatment explains the approaches psychiatric clinicians commonly use, including therapy and medication. If you want to know who you would actually be talking to, you can read about the psychiatric clinicians on our team, check whether we work with your insurance, and request an appointment when you are ready.

One thing should not wait: if your anxiety has reached the point of thoughts of self-harm or suicide, or you are in acute distress right now, call or text 988, the Suicide & Crisis Lifeline, available 24/7. If you are in immediate danger, call 911 or go to the nearest emergency room.

Frequently asked questions

How is generalized anxiety disorder different from normal stress?

Stress is usually tied to a specific situation and eases when the situation resolves. The worry described in GAD spreads across many areas of life, persists for six months or more according to the DSM-5-TR, is hard to control even when you know it's excessive, and comes with physical and mental symptoms like muscle tension, poor sleep, and trouble concentrating.

How long do symptoms need to last for a GAD diagnosis?

The DSM-5-TR requires excessive worry on more days than not for at least six months. That doesn't mean you should wait six months to seek help — a clinician can evaluate your symptoms at any point, and distressing worry deserves attention regardless of whether it ultimately meets the criteria for GAD.

Can anxiety really cause physical symptoms like chest tightness or nausea?

Yes, anxiety can produce very real physical symptoms, including muscle tension, stomach upset, chest tightness, a racing heart, and dizziness. That said, new or severe physical symptoms — especially chest pain or trouble breathing — should always be evaluated medically first, so other causes can be ruled out before anxiety is considered the explanation.

Can children and teens have generalized anxiety disorder?

Yes. The DSM-5-TR includes GAD in children and adolescents, and notes that children need only one of the six accompanying symptoms rather than the three required for adults. In younger people, the worry often centers on school performance, competence, or catastrophic events.

Can I have GAD and depression at the same time?

Anxiety and depression commonly occur together, and they share several symptoms — fatigue, poor concentration, irritability, and sleep problems among them. A careful evaluation helps a clinician understand whether one, the other, or both are present, because that distinction shapes the treatment conversation.

Will generalized anxiety disorder go away on its own?

Worry naturally waxes and wanes for everyone, and stressful seasons of life end. But if a persistent pattern of excessive, hard-to-control worry has lasted months, the more useful question is not whether to wait it out but whether an evaluation could help you understand what's happening. Anxiety has well-studied, effective treatments — and a clinician can walk you through which ones might fit.

Should I go to the emergency room for anxiety symptoms?

Go to the emergency room or call 911 for symptoms that could signal a medical emergency — chest pain, difficulty breathing, fainting — or if you are in immediate danger of harming yourself. For acute emotional distress or thoughts of suicide, you can call or text 988 anytime. For persistent but non-emergency anxiety symptoms, an outpatient evaluation is usually the right starting point.
