Inferiority complex is a persistent feeling of inadequacy that affects an individual's self-esteem and relationships, often mistaken for low self-confidence. It can be caused by factors such as lack of parental guidance, social discrimination, and physical challenges, leading to symptoms like social withdrawal, attention-seeking behavior, and high sensitivity to criticism. Strategies to combat inferiority complex include self-kindness, recognizing personal strengths, fostering positive relationships, and learning to assert personal boundaries.
