The short version

Anxiety is a sustained, often-low-grade state of worry, tension, or unease that can last hours, days, or longer. Panic attacks are sudden, intense surges of fear with strong physical symptoms that peak within about 10 minutes and then subside. Both are common. Both are treatable. They often coexist, but they’re not the same condition.

What anxiety actually feels like

Anxiety lives in the background. It’s the racing mind that won’t shut off when you’re trying to sleep. The chest that’s a little tight all day. The voice that runs through tomorrow’s meeting on a loop. The avoidance — declining the dinner, putting off the email, not driving on the highway anymore.

Common features of anxiety:

• Persistent worry that’s hard to control or stop
• Muscle tension, restlessness, or fatigue
• Difficulty concentrating — mind goes blank or jumps around
• Sleep problems, usually trouble falling asleep
• Irritability, edginess, “wired but tired”
• Avoidance of triggers, which slowly shrinks your life

The official diagnosis here is usually generalized anxiety disorder (GAD), social anxiety disorder, or specific phobia, depending on what you’re worried about and when.

What a panic attack actually feels like

A panic attack is sudden, often out of nowhere, and physically intense. People describe it as feeling like a heart attack, suffocating, or going crazy — even when they cognitively know they’re not. It builds rapidly, peaks within about 10 minutes, and then gradually subsides. The whole experience usually lasts 20–30 minutes, though the exhaustion afterward can last hours.

Typical panic-attack symptoms:

• Racing or pounding heart, palpitations
• Shortness of breath or feeling smothered
• Chest pain or pressure
• Sweating, shaking, chills, hot flashes
• Nausea or stomach distress
• Dizziness, lightheadedness, or feeling faint
• Numbness or tingling in hands, feet, or face
• Feelings of unreality or detachment
• Intense fear of dying, losing control, or “going crazy”

The official diagnosis here is panic disorder when attacks recur and you start changing your life to avoid them.

Why telling them apart matters

The treatments overlap but aren’t identical. SSRIs (escitalopram, sertraline, others) work for both, but the approach to therapy differs:

• For anxiety, we usually focus on cognitive-behavioral therapy that targets worry patterns, relaxation skills, and exposure to avoided situations.
• For panic, the most effective therapy is interoceptive exposure — deliberately bringing on the physical sensations of panic in a controlled way until they no longer trigger fear. Counter-intuitive, but extremely effective.

Mixing these up can mean undertreatment. People with panic who only get general anxiety treatment often plateau. People with anxiety who get pushed too quickly into panic-style exposure can find treatment overwhelming.

A note on benzodiazepines

Medications like Xanax (alprazolam) or Ativan (lorazepam) can stop a panic attack quickly, which makes them feel like the answer. They’re not, for most people. They work fast but don’t fix the underlying pattern, can become habit-forming, and can make panic worse over time by teaching your brain that the only way out of a panic attack is a pill. We use them sparingly and short-term, usually as a bridge while longer-term treatment takes effect.

When to come in

Panic disorder is one of the most treatable conditions in psychiatry — most people respond well to a 12-week course of CBT plus, when needed, medication. Generalized anxiety responds slightly more slowly but the trajectory is just as good. The longer either condition goes untreated, the more avoidance accumulates and the bigger the eventual unwinding. Earlier is better.
