I honestly am beginning to feel terrified of my narcissistic sister. I just feel like with everything I do and say she gets more power and more things to use against me. I'm afraid of how she will make me look in front of other people. Our birthday is in a few months and it's on thanksgiving so it's likely we will celebrate with extended family. I feel afraid of what she might do or say in front of our extended family.
I know how that feels. My mother is also very narcissistic and she has the tendency to say whatever comes to her mind, no matter if it's hurtful to others or not. My mother has fat shamed me in front my my entire family before so I totally get it. I wish you the best of luck and I hope that whatever she does or says isn't to terribly bad.
