How Anxiety Shapes Daily Life & What Effective Treatment in Florida Looks Like

What Is Anxiety?

Anxiety is the body’s typical response to real or perceived danger — a helpful, sometimes necessary response that allows the brain to prepare to deal with whatever is coming.[2] However, clinical anxiety is very different. It is an abnormal pattern of over-worrying or fearful thinking and physical activation that occurs out of proportion to actual circumstances, persists for months, and interferes with everyday life.[3] The American Psychiatric Association recognizes several types of anxiety disorders, each with overlapping but distinct presentations.[4]

Anxiety disorders affect roughly 1 in 5 adults in the United States in any given year, making them the most common mental health conditions in the country.[5] They are also highly treatable. Unfortunately, they often go untreated for years, partly because the symptoms feel like personality and the difficulty in finding the right support.

What Causes Anxiety?

There is no single cause for anxiety disorders. Multiple studies have indicated that there are many possible contributors to developing anxiety disorders and that they are likely to be interrelated, including:

• Genetics: Anxiety disorders tend to run in families, and twin studies suggest a significant hereditary component.[6]
• Brain chemistry: Differences in how the brain regulates neurotransmitters such as serotonin, GABA, and norepinephrine play a major role in the development of anxiety disorders.[7]
• Trauma History: People who suffer from trauma have an increased potential for developing an anxiety disorder later in life.[8]
• Chronic stress: Long-term exposure to high-stress environments can dysregulate the nervous system in lasting ways.[9]
• Medical Conditions: Certain medical conditions, such as hypothyroidism, heart disease, and other medical issues, can lead to or increase anxiety symptoms.[10]
• Substance use: Alcohol, amphetamines, and withdrawal from many substances can lead to or worsen anxiety.[11]
• Personal Characteristics: High reactivity and perfectionist personality traits appear to contribute to a person’s likelihood of developing an anxiety disorder.[12]

For most people, anxiety develops through some combination of these factors rather than from any single cause.

Types of Anxiety Disorders

The main anxiety-spectrum conditions include:

• Generalized anxiety disorder (GAD) is a persistent state of excessive worry concerning general everyday things such as work, relationships, health, and finances, regardless of whether there are legitimate reasons for concern. 
• Panic disorder includes recurring panic episodes that typically begin suddenly and intensely and are often unprovoked. Panic attacks have different physical symptoms, including rapid heartbeat, shortness of breath, dizziness, and chest pain. 
• Social anxiety disorder is a severe fear of being judged negatively by others in social situations. 
• Phobias are extreme and often irrational fears of specific objects, places, or events.
• Agoraphobia is the fear of places or situations that might cause panic, often leading to avoidance
• Separation anxiety disorder is significant distress when separated from attachment figures

Obsessive-compulsive disorder (OCD), acute stress disorder, and post-traumatic stress disorder (PTSD) are also closely related to anxiety, and all involve similar brain chemistry and treatment approaches.

Signs and Symptoms of Anxiety

Symptoms of anxiety show up both physically and mentally. 

Some common symptoms include:

Cognitive and emotional

• Persistent worrying
• Racing thoughts
• Difficulty focusing and concentrating
• Irritability
• Sense of impending doom
• Restlessness and feeling “on edge”

Physical symptoms

• Elevated heart rate
• Shortness of breath
• Muscle tension
• Headaches
• Gastrointestinal issues
• Sweating
• Trembling
• Dizziness
• Fatigue

Behavioral symptoms

• Avoidance of specific triggers and situations that may cause anxiety
• Seeking reassurance from others
• Difficulty making decisions
• Perfectionism
• Procrastination
• Difficulty sleeping (trouble falling asleep, waking often, racing thoughts before bed)

• Unrefreshing sleep

Panic attack symptoms

• Sudden onset of intense fear and anxiety
• Chest pain
• Shortness of breath
• Numbness
• Feeling detached from reality

If the symptoms described above continue for six months or longer and begin to negatively impact relationships, employment, or daily functioning, seeking help from a licensed healthcare professional may be warranted.

Anxiety and Addiction

One of the most studied and documented relationships in mental health research is the relationship between anxiety and substance addiction. Studies consistently indicate that anxiety disorders are strong predictive factors for developing substance use disorders, and the two conditions occur together at extremely high rates.[13]

This is because many substances initially help with symptoms — alcohol reduces immediate anxiety, benzodiazepines act directly upon the GABA receptors responsible for anxiety, and marijuana and opioids provide feelings of relaxation, calm, and distraction. However, eventually the brain adjusts to the chronic chemical interventions, creating worsened anxiety between uses and increasing dependency on those same chemicals to maintain a normal baseline state.[14]

The pattern is especially common with alcohol, benzodiazepines, and cannabis, the substances most frequently used to self-medicate. The result is a difficult cycle: anxiety leads someone to use substances, the substance use worsens anxiety symptoms over time, and the person ends up dependent on those substances that are worsening the anxiety they were initially taken to manage.

Treating people with co-occurring anxiety and substance use disorders using integrated dual diagnosis treatment is much more effective than treating either condition individually.[15]

When to Get Help With Anxiety

Some level of anxiety is normal and just part of being human. However, anxiety becomes a clinical concern when it persists, intensifies beyond what would normally be considered acceptable, or interferes with daily life. 

Consider seeking professional help if you:

• Have persistent worry, panic, or physical symptoms that have lasted for months
• Are avoiding work, social, or daily activities due to anxiety
• Use substances as a way to cope with your anxiety
• Experience sleep, eating, or relationship problems associated with anxiety
• Are having panic attacks that feel out of control
• Feel anxious about how much your anxiety is dictating your lifestyle

Anxiety responds well to treatment, and earlier intervention almost always produces better outcomes.
