In the context of dissociative disorders like OSDD (Other Specified Dissociative Disorder) or DID (Dissociative Identity Disorder), individuals may experience the presence of different identities or "alters" that have distinct characteristics, memories, and behaviors. It's important to note that the experiences of individuals with these disorders can vary widely, and not all people with OSDD or DID will have the same symptoms or alters.
Regarding the question of getting PTSD from an alter who harms you every day, it's important to recognize that alters are considered to be part of the same person and not external entities. If an alter is causing harm or distress to the individual or other alters within the system, it is typically seen as a manifestation of internal conflict or unresolved trauma within the person's mind.
In such cases, it's not necessarily that the alter itself is "evil," but rather it may represent unresolved emotions, traumatic experiences, or coping mechanisms that have developed as a response to past trauma. The alter's harmful behavior may be a way of coping with their own pain or fear. It is not common to attribute intent or moral qualities, such as being "evil," to alters.
While a harmful or distressing alter could potentially contribute to the development of symptoms like post-traumatic stress disorder (PTSD), it's more accurate to view it as a complex interplay of trauma-related factors within the individual's psyche, rather than attributing it solely to one alter.
Treatment for OSDD or DID typically involves working with a mental health professional experienced in dissociative disorders. Therapy may focus on understanding and integrating different alters, addressing past traumas, and learning healthier coping mechanisms. It's crucial to provide a safe and supportive environment for individuals with these disorders, recognizing that their experiences are often deeply rooted in trauma and complex defense mechanisms.
