this is a link for Child Abuse survivor PTSD. It is a little different from normal PTSD mainly as the victim has no "normal" to judge things by. I rate everyone but the somatic pain. I am much better now but it was a huge " albatross" to drag around.
One of these issues is trust. Once the light globe goes on, you realize that you have been lied to throughout your life. What that means is someone has just stolen it. When I was a child, my identity was the sick kid. At school there were fast kids, fat kids, strong kids, handsome kids, smart kids, ... me I described myself with great pride that I was a "Chronic Bronchitic". It was who I was. It made me different and gave me my identity.
I became very good at lying, it solved many issues, and I stole a lot (my mother starved me). I was not a nice child, but I was concentrating on surviving, future consequences were managed, but survival was critical.
What is the daughters weight, and what does she steal ??
If I look at the definition of narcissist, I was not, never was, but I only thought of myself, it was a self preservation thing. Please check the definitions of narcissism and think whether she is just prioritizing herself.
With her illness was she just sick or was their an emotional element to it. You have "X"and therefore if we cannot get "Y", you will die, be sick forever, be in pain forever ?? Can be very scary.
Did she have confidence in any doctors or her mother to make her better (I was always confident she could make me better - I never blamed her). This made a huge bond between us. Even though she was brutally sadistic when I was sick I was cared for, therefore I enjoyed being sick, more than being healthy. I was never physically abused when sick. This is me, and not the daughter but as a MBP victim your thinking is scrambled. What was her bond with her mum like ??
I am still thinking, but as you can see, the more I can hear the better the advice.
One thing I have found our in following all MBP cases I can find for last 20 years, they are all different, but they have some common threads.
