Malachite,
I have a narcissitic mother, so I'll offer you my insight from that perspective.
I came to the conclusion by talking with my T about my mom, and how much she frustrated me. I felt like she never heard me when I was talking about myself.
I am dealing with it by learning to better care for myself and my own needs, rather than relying on support from without. I am *trying* to find compassion for her, but that is taking a lot longer.
It has helped me to think of her like a drug addict -- she is addicted to herself. It is a disease. I am not to blame, and she may never realize how she impacts other people.
No matter what -- a few sessions with a good T would probably be very useful.
HTH
