What is a sister complex?

A sister complex, also known as sister complex syndrome or brother complex, is a psychological term used to describe an excessive attachment to or preoccupation with one's sister or brother. This can manifest as feelings of intense love, admiration, protectiveness, or jealousy towards the sibling.

Sister complex often stems from early childhood experiences, such as a strong emotional bond formed with a sister or brother, absence of parental guidance or attention, or experiences of trauma or neglect. These early relationships can shape a person's perceptions and behaviors towards siblings in ways that may be considered unhealthy or inappropriate.

Symptoms of a sister complex may include possessiveness, dependence, pathological jealousy, and an inability to establish healthy boundaries in the sibling relationship. Individuals with a sister complex may struggle in forming or maintaining romantic relationships due to these unresolved feelings towards their sister or brother.

Therapy can be beneficial for individuals dealing with a sister complex, as it can help them understand and address the underlying causes of their attachment to their sibling and learn healthier ways to navigate their relationships. Family therapy may also be helpful in addressing any dynamics or patterns that contribute to the development of a sister complex.
