When we begin to unpack the many reasons for a nervous system to hold onto things long after they seem to be helpful, they are all rooted in survival. The brains' main purpose is to keep us alive. Therefore, it’s our job as psychotherapists to invite curiosity and help identify the function of the dysfunction. A good way to check is to ask ourselves, “Based on what I know about them, how do their symptoms make sense?"
If you cannot answer this question based on your training, knowledge of the nervous system, the AIP model, and other theories of human development, it may be a good time to pause reprocessing and gather more information or add more specific resources for your client.
Our brains are hardwired for survival and designed for resilience. However, in order for our systems to make adaptive change, we have to convince our brains that the new way of being is not a direct threat to our survival. When it comes to getting stuck in processing, sometimes offering a general nudge or shift in perspective is all we need to help facilitate profound change in the neural network. If the client's brain keeps bringing the system back to the same point…there is a good reason for that. I encourage you to respect the system and look for other ways to offer the same level of safety through better understanding and validation of the function of that dysfunction or the creation and combination of a more adaptive way to provide the same function.
One way to think about it would be if your house needs major repairs to be safe or up to code, how you approach the project greatly depends on whether or not you have another place to stay while the project is being completed. If you have to live in the house during the remodel, we are going to have to approach the project much more carefully, constantly thinking about the function of each beam, appliance and how we limit access to parts of the house as we go. We don’t want to have someone get hurt or not be able to function in their day to day lives in the process of trying to fix up their house.
