Feeling anxious is an overwhelming emotion, and we all feel it from time to time. The simplest way to understand anxiety is as a stress response — also known as “fight or flight” mode.
While it might sound counterintuitive, anxiety can occasionally serve a purpose — like when you recognize a potentially life-threatening situation and take swift action to avoid it.
However, once that threat or stressful moment passes, the anxiety usually disappears. For some people, anxiety can get extreme and outlive its short-term helpfulness to the point that it’s debilitating.
So, if your anxiety is persistent or crops up when there’s no apparent reason, you might be wondering, “How long does an anxiety disorder last?”
The answer is it depends on the person. An anxiety disorder can last anywhere from a few months to many years. It will go away completely for some, and for others, it may be a lifelong condition to treat. Keep reading to learn more and find out about the manageable factors.

Approximately 31.1% of American adults will develop an anxiety disorder at some time in their lives¹.
The medical definition of an anxiety disorder is when worrying stops you from functioning normally, is out of proportion to the circumstances, and you experience it most days, for six months or longer¹.
Anxiety disorders are generally associated with having constant and excessive fear or worry in everyday life, with an urge to avoid situations connected to this fear.
Unlike the occasional bout of anxiousness, chronic anxiety doesn’t come and go on its own—the stress response is constantly activated.
There are several types of anxiety disorders. These include:
Generalized anxiety disorder: Constant and excessive worry or stress that interferes with everyday activities
Panic disorder: Recurring, sudden panic attacks, accompanied by physical and psychological distress
Social anxiety disorder: Overwhelming worry and discomfort in social situations, with a fear of embarrassment, rejection, humiliation, or being looked down upon
Phobias: Intense and persistent fear of a certain thing(s) or situation(s), out of proportion to the actual threat
Separation anxiety disorder: Extreme fear of separation from a person or fear that something terrible will happen to a loved one
Anxiety can make you feel tense or worried, and you may notice that it heightens your alertness.
There is no set timeframe for how long an anxiety disorder is expected to last, it is highly individual. However, there are some known factors you should be aware of.
According to one three-year study² factors for anxiety disorder duration include:
Being in an older age group
Lacking a paid job
Having a physical disorder or poor physical functioning
How quickly you’re diagnosed and treated
The type of anxiety disorder (social anxiety disorder tends to have a longer duration and slower response to treatment)
Having multiple anxiety disorders
One of the guidelines for diagnosing generalized anxiety disorder is having severe, persistent anxiety and symptoms for at least six months.
From the time of diagnosis, an anxiety disorder can last from a few months to many years.
Most people will have symptoms of an anxiety disorder for a long time before seeking professional help, sometimes up to 15 years³.
Without any intervention, anxiety disorders can worsen over time and prolong the impact on your everyday life.
The evidence indicating how long anxiety disorders tend to last shows mixed results. Anxiety disorders can be long-lasting, but full recovery is also possible.
Data from the Netherlands Mental Health Survey and Incidence Study-2⁴ indicates
The median duration of an anxiety disorder is around 7.5 months⁴
Some studies⁵ report that generalized anxiety disorder follows a pattern of recovery and relapse for up to 20 years.
Even after recovering from an anxiety disorder, you will still experience anxiousness. However, instead of the persistent symptoms of a disorder, you will feel occasional anxiety that switches “on” and “off” in response to stress.
Some people experience a relapse even after they appear to have recovered from anxiety. Statistically, this seems most likely to happen after the 3-year⁵ point of treatment and recovery.
In response to stopping anxiety medication
It can be tempting to stop medicating your anxiety once you start to feel better. However, it’s vital to speak to your doctor before making any changes. Medications usually take time to work, but once they start, they continue to have a beneficial effect over time.
A third⁶ of people who suddenly stop taking antidepressants midway through treatment relapse.
Suddenly stopping medication can also cause withdrawal symptoms that closely mimic anxiety.
Other possible factors include:
Stressful life events
Other mental health conditions
Having anxiety-like symptoms that don’t quite meet the diagnostic criteria for having a disorder
Finding constructive ways to cope with your anxiety disorder can empower you to return to your usual activities and feel positive about your well-being and relationships.
Here are some evidence-based ways to help you live with and recover from anxiety:
See a healthcare professional
A healthcare professional can help you undergo a mental health assessment and offer various treatment options or medications. This can be your main doctor or a psychiatrist.
The sooner you explore treatment options, the better your outcome is likely to be.
Exercise and make other lifestyle changes
Making lifestyle changes such as regular exercise, prioritizing sleep, stepping away from social media, eating a balanced and nutritious diet, reducing or eliminating alcohol and caffeine intake, quitting smoking, and maintaining a good support network can all help manage your anxiety.
Stick to your recommended treatment plan
This may involve taking medications as prescribed, going to appointments, or following up on homework between therapy sessions.
If you have any concerns about your treatment or experience any side effects, it’s important to discuss this with your doctor before making any changes.
Psychotherapy (talk therapy)
Psychotherapy helps to manage both the physical and psychological aspects of anxiety disorders.
A well-known and effective type of psychotherapy is cognitive behavioral therapy (CBT). CBT helps you understand the connections between your thoughts, feelings, and behavior.
It teaches you to identify unhelpful thought patterns and learn coping mechanisms for anxiety-provoking situations.
Over time, as you improve, the focus will shift to learning how to recognize and manage relapses.
CBT is not an instant fix and requires a commitment to regular sessions with tasks in between sessions. 12–16 weekly sessions are usually sufficient, but your therapist should discuss the recommended duration of treatment based on your needs.
Often, improvements are seen somewhere between 4–6 weeks⁷.
Relaxation and breathing exercises and mindfulness meditation can help to reduce the physical symptoms of anxiety and make them feel less overwhelming. These techniques also bring your attention to the present moment and help you to ruminate less on the past and future.
Antidepressants, including selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), are evidence-based effective medications for anxiety. However, they are slow-acting and can take 4–6 weeks to have a noticeable effect. One study³ shows that the recovery rates in participants taking paroxetine (an SSRI) reached 73% after 32 weeks of taking the medication, compared to 11% remission in the placebo group.
Beta-blockers can help manage and reduce physical symptoms of anxiety, short-term or as-needed to reduce acute anxiety. Benzodiazepines are sometimes used for the short-term management of anxiety symptoms. They work quickly and can bring relief within 30 minutes.
However, you can develop a tolerance and dependence on benzodiazepines when taken regularly. They become less effective over time and you may get withdrawal effects and increased anxiety when you stop taking them. Because of this, benzodiazepines are not the first line of treatment for anxiety disorders.
Notes on treatment
Research⁷ shows that a combination of psychotherapy and medication is a more effective long-term option, compared to just one or the other.
Anxiety disorders tend to be chronic or aggravated by periods of stress. To help you manage and prepare for difficult times, stay in close communication with your doctor or therapist.
Mental health conditions are highly individual, and so it is impossible to predict exactly how long your anxiety disorder will last. There is evidence to suggest that the median, or “middle” length of time for an anxiety disorder to last is 7.5 months, but that is one study’s findings. More research is definitely warranted.
Just remember, if you have anxiety that limits your ability to function in everyday life, many different treatment options are available. Some people can experience a full recovery, while others will improve their symptoms and significantly regain their quality of life.
