If you or someone you know is in immediate danger or experiencing thoughts of suicide, call or text 988 to reach the Suicide & Crisis Lifeline, or call 911. The National Rehab Hotline at (866) 210-1303 is for non-emergency information, support and referrals.
Anxiety is the most common mental health condition in the United States and one of the most misunderstood. The racing thoughts, the tight chest, the nights of broken sleep, the feeling of dread that doesn’t have a clear cause: these aren’t character flaws or signs of weakness. They’re symptoms of a treatable medical condition that affects tens of millions of Americans every year.
According to the National Institute of Mental Health, an estimated 31.1% of U.S. adults experience an anxiety disorder at some point in their lives and 19.1% meet criteria in any given year. Anxiety affects work, relationships, sleep and physical health, and it often shows up alongside other conditions, including substance use disorders, in ways that can make recovery feel out of reach. It doesn’t have to.
This page covers what anxiety disorders are, how to recognize the signs, why anxiety and substance use so often appear together and what treatment looks like. If you’re ready to talk through your situation with someone, the National Rehab Hotline is available 24-7 at (866) 210-1303, free and confidential.
Understanding Anxiety Disorders
Anxiety itself isn’t a disorder. It’s a normal human response to stress, danger or uncertainty. The fight-or-flight response that floods your body before a job interview or a difficult conversation is anxiety doing exactly what it evolved to do.
Anxiety becomes a disorder when it shows up too often, lasts too long, appears without a clear external cause and interferes with daily life. The key difference is how much it affects your life: when anxiety starts affecting your work, relationships, sleep or ability to function, it’s no longer just stress.
Anxiety disorders are highly treatable. With evidence-based therapy, medication when appropriate and the right support, most people see meaningful improvement. The harder part, for many, is recognizing that what they’re experiencing is treatable in the first place.
Common Types of Anxiety Disorders
“Anxiety disorder” isn’t one condition. It’s a category. The most common types include:
Generalized Anxiety Disorder (GAD)
Persistent, excessive worry about everyday concerns, including work, health, finances and family, that occurs more days than not for at least six months. People with GAD often describe their worry as uncontrollable, even when they recognize it’s out of proportion to the situation.
Panic Disorder
Recurrent, unexpected panic attacks, with sudden surges of intense fear or discomfort that may include physical symptoms like racing heart, shortness of breath, dizziness and a sense of impending doom. Panic disorder includes ongoing worry about when the next attack will come.
Social Anxiety Disorder
Intense fear of social situations where you might be judged, embarrassed or scrutinized. Social anxiety disorder is more than shyness. It can lead people to avoid school, work, dating and other situations central to a normal life. An estimated 12.1% of U.S. adults experience social anxiety disorder at some point in their lives.
Specific Phobias
Intense, irrational fear of a specific object or situation, such as heights, flying, enclosed spaces, certain animals, blood or needles. The fear is out of proportion to the actual danger and often leads to avoidance.
Agoraphobia
Fear and avoidance of places or situations that might cause panic, helplessness or embarrassment, typically open spaces, crowds, public transportation or being away from home. In severe cases, people may become unable to leave their house.
Separation Anxiety Disorder
Excessive fear or anxiety about being separated from people you’re attached to. Long classified as a childhood condition, separation anxiety disorder is now recognized in adults as well.
Signs and Symptoms of Anxiety
Anxiety usually shows up in three main areas: physical, emotional and behavioral. Most people experience symptoms in all three, though the mix varies.
Physical Symptoms
- Racing or pounding heart
- Shortness of breath or feeling like you can’t get a full breath
- Tight chest, muscle tension or persistent headaches
- Trembling, sweating or hot flashes
- Nausea, stomach pain or digestive problems
- Fatigue and difficulty sleeping (falling asleep, staying asleep or both)
- Feeling restless, on edge or unable to relax
Emotional and Cognitive Symptoms
- Persistent worry that’s hard to control or shut off
- Feeling of dread or that something bad is about to happen
- Difficulty concentrating or feeling like your mind goes blank
- Irritability or feeling on edge
- Anticipatory anxiety, including worrying about future situations long before they arrive
Behavioral Symptoms
- Avoiding situations, places or people that trigger anxiety
- Procrastination or freezing on tasks
- Reassurance-seeking, including repeatedly asking others to confirm everything is okay
- Compulsive checking or rituals to reduce anxiety
- Self-medicating with alcohol, cannabis or other substances
Causes and Risk Factors
Anxiety disorders don’t have a single cause. Most arise from a combination of biological, psychological and environmental factors:
- Genetics. Anxiety disorders run in families. Having a close relative with an anxiety disorder increases your risk.
- Brain chemistry. Differences in neurotransmitter systems (especially serotonin, GABA and norepinephrine) play a role.
- Trauma and adverse life events. Childhood adversity, abuse, neglect or major life stressors are strong predictors.
- Chronic stress. Sustained high-stress environments can shift the body’s threat-response systems into a state of constant alert.
- Medical conditions. Thyroid issues, heart conditions and chronic illnesses can produce or worsen anxiety symptoms.
- Substance use. Alcohol, stimulants, cannabis and certain medications can trigger or amplify anxiety, especially during withdrawal.
The Link Between Anxiety and Substance Use
Anxiety and substance use disorders often happen together at high rates. According to the National Institute on Drug Abuse, roughly half of people who experience a mental illness will also experience a substance use disorder at some point in their lives, and the inverse is also true. Anxiety disorders are among the most common conditions appearing alongside substance use.
The relationship runs in both directions. Many people with untreated anxiety turn to substances to manage symptoms, including alcohol to quiet racing thoughts, cannabis to sleep and benzodiazepines to take the edge off social situations. This pattern, sometimes called self-medication, can produce short-term relief but tends to worsen anxiety over time. Drinking to manage anxiety is one of the most common and most studied examples of how this dynamic plays out.
Substance use can also produce or amplify anxiety. Stimulants like cocaine and methamphetamine can make anxiety much worse. Benzodiazepine use, even when prescribed, can create rebound anxiety between doses that’s worse than the original symptoms. Withdrawal from alcohol, opioids and other depressants often includes severe anxiety.
When anxiety and substance use occur together, the clinical term is dual diagnosis, and the most effective treatment addresses both conditions at the same time. Treating one without the other typically leads to relapse, either back into substance use or back into untreated anxiety symptoms that drive the next round of self-medication.
Treatment Options for Anxiety
Anxiety disorders are among the most treatable conditions in mental health. Most people respond well to a combination of therapy, medication and lifestyle changes.
Therapy
Cognitive behavioral therapy (CBT) is the gold standard for most anxiety disorders. CBT helps people identify the thought patterns that fuel anxiety and learn practical skills for responding to them differently. For specific phobias and certain anxiety disorders, exposure therapy can be highly effective. It’s a structured, gradual approach to facing feared situations. Acceptance and commitment therapy (ACT) and dialectical behavior therapy (DBT) are also evidence-based options.
Medication
Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are the most commonly prescribed medications for anxiety disorders. They take several weeks to reach full effect but are non-addictive and generally well-tolerated. Benzodiazepines are sometimes prescribed for short-term relief of severe anxiety, but they carry meaningful dependence and withdrawal risks, particularly for anyone with a history of substance use disorder.
Lifestyle and Self-Care
Regular exercise, consistent sleep, reduced caffeine, mindfulness practices and strong social connections all reduce anxiety symptoms. These aren’t substitutes for treatment when an anxiety disorder is present, but they can make therapy and medication work better.
Integrated Treatment for Co-Occurring Conditions
When anxiety and substance use occur together, the most effective approach is integrated dual diagnosis treatment, with therapy and medical care that addresses both conditions in the same setting. Treating anxiety in a substance use program, or substance use in a mental health program, without coordination between the two tends to produce worse outcomes than integrated care.

FAQ: Anxiety and Mental Health Support
- How Do I Know If My Anxiety Is Normal or a Disorder?
Everyone experiences anxiety. The question is whether it’s interfering with your life. If anxiety regularly affects your sleep, work, relationships or daily functioning, or if it lasts longer or feels more intense than situations seem to warrant, it’s worth talking to a mental health professional. Diagnosis isn’t about labeling normal feelings as disordered; it’s about identifying when treatment can genuinely help. - Can Substance Use Cause Anxiety, or Does Anxiety Cause Substance Use?
Both can happen, often at the same time. Many people with untreated anxiety turn to substances for relief, and many substances either trigger or worsen anxiety, especially stimulants, alcohol withdrawal and the gaps between benzodiazepine doses. The two conditions tend to reinforce each other, which is why integrated treatment that addresses both matters. - What Is the Most Effective Treatment for Anxiety Disorders?
For most anxiety disorders, cognitive behavioral therapy (CBT) is the most evidence-supported treatment, often combined with an SSRI or SNRI medication. The right combination depends on the specific disorder, severity and individual factors. For people with co-occurring substance use disorders, integrated dual diagnosis treatment produces the best outcomes. - Are Anxiety Medications Addictive?
Most modern anxiety medications, including SSRIs and SNRIs, are not addictive and are safe for long-term use. Benzodiazepines, sometimes used for short-term severe anxiety, do carry meaningful dependence and withdrawal risks and are generally avoided for anyone with a history of substance use disorder. A prescriber who knows your full history is the right person to weigh medication options with you. - When Should I Call 988 Instead of the National Rehab Hotline?
Call or text 988 if you’re in crisis, including having thoughts of suicide or self-harm, feeling unable to keep yourself safe or experiencing an acute mental health emergency. Call the National Rehab Hotline at (866) 210-1303 for non-emergency support, treatment information and referrals, including for anxiety, substance use or both. - What Happens When I Call the National Rehab Hotline?
You’ll speak with a trained representative who can listen, answer questions and connect you with treatment resources for anxiety, substance use or co-occurring conditions.
