What is a common name for a strong irrational fear that is difficult to eliminate?

The correct term for a strong, irrational fear that is difficult to eliminate is phobia. Phobias are classified as anxiety disorders and are characterized by an overwhelming and debilitating fear of a specific object, situation, or activity that poses little to no actual danger. Individuals with phobias often go to great lengths to avoid the feared object or situation, which can significantly impact their daily lives.

Phobias can develop from traumatic experiences, learned behaviors, or may even arise without any clear trigger. Their irrationality and intensity distinguish them from other types of fear, making them challenging to overcome without therapeutic intervention. Treatments for phobias typically include cognitive-behavioral therapy (CBT), exposure therapy, and sometimes medication.

In contrast, stress refers to the body's response to a demand or challenge and does not specifically denote a fear. Psychosis involves a disconnection from reality and does not focus on irrational fears. Trauma relates to experiences of extreme distress or suffering and can lead to anxiety or phobic reactions, but it is not synonymous with the persistent, irrational fear characteristic of phobias.
