When you accept the diagnosis of PNES you are accepting the basic fact that the seizures are happening because of severe trauma. Often this trauma was abuse at the hands of someone in your childhood. Sometimes it was caused by someone in your adulthood. My wife was sexually, physically and emotionally abused and had seizures as a defense mechanism. They helped her survive the abuse that she was too small to escape from.
Many years later when she was an adult she started working on healing from the abuse and trauma she suffered as a child. She was experiencing depression and flashbacks and knew these were related to the original abuse. Her seizures returned when the flashbacks grew too vivid. They were as real to her as the original abuse. Her mind/body utilized the seizures as a protective shield. She made the connection that the seizures were caused by this past abuse and by accepting this fact she was better able to respond to treatment.
It can be extremely painful and difficult to accept past trauma. This can lead to not accepting that the diagnosis of PNES is accurate. The fear and pain of the diagnosis may lead some to look for many other opinions in the hope that they will find a medical answer to this psychological problem.
The key to overcoming PNES is the acceptance of the diagnosis and by understanding their original cause. Trauma and abuse is often inflicted on us by others. They are the ones who are responsible for perpetrating the violence against you. You have survived though due to your courage and strength which allowed you to cope with the pain that was too great to bear. You need to draw on those qualities again and begin the path of healing.
