I can provide some general information on this topic.
In DID, becoming aware of the alters and their roles in the person's life is an essential aspect of therapy. By understanding the different alters and their unique characteristics, needs, and functions, individuals may gain more control over their identity and behavior. This process is known as "integration," where the goal is to develop better communication and cooperation between alters and, in some cases, work towards a more unified sense of self.
However, the process of integrating alters can be complex and may not always result in a single alter taking control in different situations. Each alter may serve a purpose and have different coping mechanisms for specific situations, so integration doesn't necessarily mean only one alter will emerge in all circumstances.
When an alter is sabotaging something, it might indicate that they are experiencing distress or conflict within the system (the collective term for all alters). In such situations, it's crucial to seek help from a qualified mental health professional who has experience in working with dissociative disorders. Therapy can help explore the reasons behind the alter's behavior and address any underlying trauma or unresolved issues that may be contributing to their actions.
Coping with an alter sabotaging something may also involve increasing communication and cooperation between alters. Techniques such as journaling, communication exercises, and creating a safe internal environment for the alters to express themselves can be helpful.
Again, I cannot stress enough that if you or someone you know is dealing with issues related to dissociation or alters, it's essential to consult with a mental health professional who can provide personalized guidance and support. They can work with you to develop coping strategies tailored to your specific situation and needs.
