Final answer:
Individuals desiring social contact but held back by insecurity may struggle with intimacy versus isolation, a concept by Erik Erikson, wherein a strong sense of self is critical to forming intimate relationships. Without it, such individuals may experience loneliness and emotional isolation.
Step-by-step explanation:
People who desire social contact but are held back by insecurity are often grappling with Erikson's stage of intimacy versus isolation, which is particularly relevant in early adulthood. According to the psychologist Erik Erikson, it is crucial for individuals to develop a strong sense of self during adolescence to form healthy and intimate relationships in adulthood. However, individuals who fail to develop a positive self-concept may find themselves desiring social contact but struggle with insecurities that prevent them from achieving the intimacy they seek. This can result in feelings of loneliness and emotional isolation.
