Anxiety attacks can feel overwhelming and frightening. They often come on suddenly, bringing a mix of intense mental and physical symptoms that can leave you feeling out of control.  

Understanding anxiety attacks 

Anxiety attacks, also known as panic attacks, are sudden episodes of intense fear or discomfort. They can happen without warning and may not always have a clear cause. While everyone’s experience is unique, there are common signs to look out for.

What does an anxiety attack feel like? 

During an anxiety attack, you might feel an overwhelming sense of fear or dread. Some people describe it as feeling like they are dying or having a heart attack. The symptoms can be so intense that it’s hard to believe they are caused by anxiety alone. 

Why do anxiety attacks happen? 

Anxiety attacks can be triggered by stress, certain situations, or sometimes for no obvious reason at all. They are a natural response to feeling threatened, even if there is no real danger present.
