In the context of Dissociative Identity Disorder (DID), there is no concept of an "original" personality that can die or disappear for eternity. DID does not have a clear-cut notion of an "original" self or personality from which the other identities emerge. Instead, the development of multiple identities is often a result of severe and chronic trauma during childhood, which leads to the fragmentation of memory, consciousness, and sense of self.
In DID, each identity state is considered as a distinct personality with its own thoughts, emotions, memories, and behaviors. These identities, also referred to as alters or parts, can have varying levels of awareness of each other and may even have different ages, genders, and characteristics.
It's essential to understand that DID is a coping mechanism that develops in response to trauma. The purpose of dissociation is to protect the individual from overwhelming experiences, allowing them to survive the traumatic events. Therefore, the different identity states serve as adaptive responses to the challenging circumstances the person faced during their childhood.
Treatment for individuals with DID typically focuses on helping them integrate the different identity states, achieve better communication and cooperation among them, and work through the underlying trauma. The goal is not to eliminate any particular identity but to promote better functioning, co-consciousness, and improved overall well-being. Successful treatment can lead to better integration and a more cohesive sense of self, but it does not involve the eradication of any identity.
