Narcissists have to destroy others. [View all]

My sister has been my constant narcissist since age 2. We're talking 6+ decades.

I cut off all contact with her during the summer. No fights, no words. Just separation.

I now have discovered that she's been telling others that I have Alzheimer's.

That's what narcissists do: if they can't control you, they try to control what others think about you.
