If you are searching for severe anxiety and panic attacks, you may be trying to understand whether what is happening is “just anxiety” or something medically urgent. Your heart may be racing. Your chest may feel tight. You may feel dizzy, shaky, unreal, trapped, or certain that something terrible is about to happen.
I want to say this clearly: panic symptoms can feel terrifying, and you are not weak for being frightened by them. Anxiety disorders are among the most common mental health conditions in the United States. NIMH estimates that 19.1% of U.S. adults had an anxiety disorder in the past year, and about 31.1% experience one at some point in life. (NIMH)
In this article, I will explain what panic feels like in the body, when urgent care is needed, how to think about panic versus heart symptoms, and what to do in the moment.
The Clinical Picture: What a Panic Attack Does to the Body
A panic attack is a sudden surge of intense fear or discomfort that activates the body’s alarm system. The brain and body respond as if danger is present, even when there may be no immediate external threat.
Symptoms may include racing heart, chest pain, shortness of breath, trembling, sweating, nausea, dizziness, tingling, chills, hot flashes, fear of dying, or feeling detached from reality. NIMH notes that panic attacks can include physical symptoms that feel like a heart attack, such as rapid heart rate, trembling, tingling, and other intense body sensations. (NIMH)
During my nursing career and across the healthcare system spectrum, I have met many patients who arrived at the ER convinced they were dying, only to be told it was panic. That can feel embarrassing, but it should not. The symptoms were real. The fear was real. The need for evaluation was real.
A panic attack is not “fake.” It is a real physiological event. The goal is to determine whether it is panic, a medical condition, or both.
The Contemporary Landscape: Anxiety, ER Visits, and Uncertainty
Anxiety is common, but undertreatment remains a problem. Many people live for years with panic attacks, avoidance, and shame before seeking care. Telehealth has helped some people access therapy and medication management, but many still struggle to find timely appointments.
The hard part is that panic symptoms overlap with medical emergencies. The American Heart Association lists heart attack warning signs such as chest discomfort, pain in the arm, back, neck, jaw, or stomach, shortness of breath, nausea, cold sweat, or lightheadedness. (American Heart Association) If you are unsure whether symptoms are cardiac, seek medical care.

What You Need to Know: Key Facts About Severe Anxiety
1. Panic attacks can mimic medical emergencies.
Chest tightness, shortness of breath, dizziness, nausea, and racing heart can happen during panic. They can also happen during heart or medical emergencies.
If symptoms are new, severe, different from usual, associated with fainting, weakness, chest pressure, radiating pain, or you have heart risk factors, seek medical evaluation.
2. “It is anxiety” should not be used to dismiss you.
Even when anxiety is the cause, the suffering is real. A panic attack can make a person feel trapped in their body.
Good care should help you rule out medical danger and then build a plan to treat the anxiety.
3. Anxiety becomes urgent when it prevents basic functioning.
Severe anxiety may require urgent care when someone cannot leave home, cannot sleep for days, cannot eat or drink, is using substances to cope, is self-harming, or is having suicidal thoughts because the anxiety feels unbearable.
This is not “just nerves.” It is a level of distress that needs support.
4. Grounding skills are first aid, not full treatment.
Breathing and grounding techniques can help calm the nervous system in the moment. They do not replace therapy, medication evaluation, trauma treatment, substance use care, or medical assessment when needed.
Think of them as tools to get through the next few minutes.
5. Shame keeps many people from getting help.
Many people with anxiety look “high functioning” on the outside. Inside, they may be exhausted from constant fear.
You do not have to earn help by falling apart publicly.
What to Do: Practical Steps During Severe Anxiety or Panic
1. Rule out medical danger when symptoms are new or concerning.
Call 911 or seek emergency care if you have chest pressure, pain radiating to arm/jaw/back, fainting, severe shortness of breath, weakness on one side, confusion, blue lips, overdose, or symptoms that feel medically dangerous.
It is better to be evaluated than to ignore a possible medical emergency.
2. Use the 5-4-3-2-1 grounding technique.
Name 5 things you can see, 4 things you can feel, 3 things you can hear, 2 things you can smell, and 1 thing you can taste.
This helps bring the brain back to the present moment.
3. Try box breathing.
Breathe in for 4, hold for 4, breathe out for 4, hold for 4. Repeat slowly.
If holding your breath makes you more anxious, skip the hold and simply lengthen the exhale.
4. Reduce stimulation.
Move to a quieter space if possible. Sit down. Loosen tight clothing. Sip water. Put your feet on the floor.
Tell yourself: “This is intense, but it will pass. My body is sounding an alarm.”
5. Call for crisis support if anxiety feels unsafe.
Call or text 988 if anxiety is connected to suicidal thoughts, self-harm urges, substance use crisis, or emotional distress that feels unmanageable. Text HOME to 741741 if texting feels easier.
You can also ask someone you trust to sit with you while you call.
6. Use Link4Help.org to find local support.
If anxiety has become a recurring crisis, visit Link4Help.org to browse crisis centers by state, find mobile crisis teams in your state, or search crisis hotlines by state.
If you need outpatient care after the crisis, use the directory as one starting point while also contacting your insurance plan, primary care provider, or local community mental health center.
A Note for Families and Caregivers
If someone you love is panicking, do not tell them to “calm down.” They would if they could. Try saying, “I know this feels terrifying. I am here. Let’s slow this down together.”
Keep your voice low. Reduce the crowd around them. Offer simple choices: sit or stand, call or text, lights on or off. If symptoms may be medical, do not argue them out of care. Seek evaluation.
What to Do Next
Severe anxiety can make a person feel trapped, but there are steps that help. Rule out medical danger, use grounding as first aid, call for crisis support if safety is uncertain, and seek treatment for the anxiety pattern itself.
If you need crisis guidance, call or text 988. If texting feels safer, text HOME to 741741. If you need local mental health crisis resources, visit Link4Help.org and search your state. You are not weak for needing help with anxiety. You are responding to a nervous system that has been carrying too much.
