McWilliams Psychiatry

Physician-Led Anxiety Treatment in Columbia, MD

Do you feel on edge most days? Have you noticed that worry or tension has started getting in the way of work, relationships, or simply enjoying your life? Dr. McWilliams offers direct, physician-led evaluation and treatment of adults living with anxiety in Maryland, Virginia, and Wisconsin.

What is Anxiety?

Anxiety affects more adults than almost any other psychiatric condition — yet most people suffer for years before receiving a proper diagnosis and effective treatment.

Anxiety disorders affect how you think, feel, and function in daily life. They are neurobiological conditions involving real changes in brain chemistry and circuitry, including the amygdala, the stress response system, and neurotransmitters like serotonin, norepinephrine, and GABA.

Anxiety can look different from person to person. Some patients experience constant, low-grade worry that never fully goes away. Others have physical symptoms — racing heart, chest tightness, difficulty breathing — that can be mistaken for medical problems. Many people, including professionals, remain functional on the outside while carrying a significant internal burden.

With the right evaluation and treatment — one that accounts for your full biological, psychological, and social history — most people experience meaningful, lasting improvement. Dr. McWilliams specializes in that kind of thorough, individualized care.

Generalized Anxiety Disorder (GAD)

Persistent, excessive worry about everyday situations — work, health, relationships, finances — that is difficult to control and accompanied by physical symptoms like fatigue, muscle tension, and sleep disruption.

Health Anxiety

Persistent worry about having or developing a serious illness, often despite reassurance from medical providers. Frequently misidentified as a purely physical problem before the psychiatric component is recognized.

Panic Disorder

Recurrent panic attacks with intense physical symptoms — racing heart, chest tightness, shortness of breath, dizziness — often leading to avoidance behaviors and anticipatory anxiety between episodes.

Anxiety with Depression or ADHD

Anxiety rarely occurs in isolation. It commonly co-occurs with depression, ADHD, and insomnia. An integrated evaluation is essential to avoid treating only part of the picture.
