Narcissist


Once again I’m doing Relationship work on my sister! The basic model I have is:
C Sister
T my sister is a narcissist
F cautious
A limit time with her, do not share information, do not trust her, expect the worst, accept it as a personality disorder vs malicious
R ? Im not able to experience love or love unconditionally, like a narcissist
Does this R prove the T?
Thinking of her as a narcissist feels as though it protects me, because it keeps her actions in perspective and reminds me what to expect from her. How can I evolve in my love for her while staying protected?
