I am 50 and still trying to navigate a relationship with my narcissistic, histrionic mother. No, she has never been diagnosed with anything, would never even think there is anything wrong with her. Although she does now admit to PTSD.

I have learned that she is just a contrarian. What she says constantly changes to good/bad, approval/disapproval. I have learned that I can never stay good for her. I try to be a good daughter, and I am. But, no matter what, I will still get her disapproval and anger.

I have learned to just tell her what she wants to hear and keep a safe distance. I just try to shut my mouth and let her rant. I see it as a trap she is setting to try to catch me. I tell myself to stay calm and don't say anything. I tell her the food is burning and I have to hang up the phone or something.

Your mother will never change. But you will want to continue some relationship with her because she is your mother. It is too painful to remove her from your life. Tread lightly!
