Step-by-step explanation:
A feeling of intense worry, unease, or nervousness is a symptom often referred to as anxiety. This symptom is the primary characteristic of two common psychological disorders: anxiety disorders and phobias. A phobia is a fear of a particular thing or scenario. A fear of being evaluated or judged by others is referred to as social anxiety or social phobia.
Anxiety disorders are feelings of worry and fearfulness that last for months at a time and can include conditions such as obsessive-compulsive disorder (OCD), panic disorders, posttraumatic stress disorder (PTSD), as well as social and specific phobias. It is crucial to understand that occasional feelings of anxiety are normal, but anxiety disorders are more persistent and can significantly impact one's life.
