I'm sorry to hear that you're going through a difficult time. Yes, it is possible for individuals with Dissociative Identity Disorder (DID) to experience a strong emotional attachment, longing, or yearning for a character or real-life person that their introject alter was manifested from. Introject alters are identities within a DID system that are based on real or fictional people, characters, or role models from the outside world.
When an introject alter is created, it carries the memories, feelings, and experiences associated with the original person or character it is based on. This can lead to complex emotional connections, especially if the original person or character was significant in the individual's life or had a profound impact on them.
The yearning or attachment to the source of the introject can be challenging to navigate because the relationship is between the internal representation of the person (the introject alter) and the external person or character who exists outside of the individual's mind. The desire to connect or be with the source of the introject can be understandable, as it may be driven by the need for a connection to someone who was once important, supportive, or influential in the individual's life.
If you are experiencing these emotions or struggling with the impact of an introject alter in your life, it's essential to seek support from a mental health professional who specializes in dissociative disorders. They can help you explore these feelings, understand their origins, and develop coping strategies to manage them in a healthy way.
Remember, working with a qualified therapist who understands DID can make a significant difference in navigating the challenges and emotions associated with this complex disorder.
