Excessive fear, also known as PARANOIA, is an irrational fear or anxiety that can be debilitating and interfere with a person's daily life. It is characterized by an intense feeling of fear or worry that is out of proportion to the situation. People with PARANOIA often experience feelings of being watched, judged, or persecuted, and may become overly suspicious of others. They may also have difficulty trusting people and may become isolated from society.
