Symptoms of Severe Anxiety Feel Very Scary

Symptoms of severe anxiety can be scary, and severe anxiety symptoms can significantly impair quality of life. Learn about severe anxiety symptoms.

While some people think of anxiety as an uneasy feeling in the pit of their stomach or the fear they feel when standing atop a high building, severe anxiety symptoms can be much worse and downright terrifying.

Perhaps the anxiety disorder best known for severe effects is panic disorder. A panic attack can create severe anxiety symptoms in a matter of minutes and patients are often rushed to the Emergency Room because they feel they are dying. It's important to remember though, panic attack symptoms typically peak within ten minutes and then begin to fade.

  • Overreacting with intense fear to anything reminiscent of the traumatic event
  • Feelings of a shortened life
  • Looking for and seeing danger everywhere

Behavioral Symptoms of Severe Anxiety

Behavioral symptoms of severe anxiety often take the form of avoidance. Because severe anxiety symptoms are so terrifying, people will do almost anything to avoid feeling them. This might include:

  • Not going to specific places
  • Not seeing certain people
  • Not having specific experiences

These severe symptoms of anxiety can even escalate until the person refuses to leave the house or talk to most people.

Other severe behavioral symptoms of anxiety include those seen in obsessive-compulsive disorder (OCD). People with OCD become obsessed with ideas such as:2

  • Contamination
  • Safety
  • Order
  • Doubt

Once an obsession takes hold, the person feels an overwhelming urge to perform an action, a compulsion, also known as a ritual. Examples of severe compulsions include:

  • Washing of hands until the skin is raw
  • Picking of skin and hair around the face until there are open wounds
  • Being unable to leave the house due to repeated checking of things related to safety such as turning off the stove
