Anthropophobia, stems from intense fear of judgment, embarrassment, or rejection, fueled by negative past experiences (like bullying or trauma), family history of anxiety, low self-esteem, or personality traits like shyness, leading to avoidance, physical symptoms (shaking, sweating, nausea), and difficulty with daily interactions. It's more than shyness, impacting self-confidence and daily life, but it's treatable with therapy.
