My sister-in-law is a totally manipulatively, self-centered narcissist and borderline psychopath. She has ZERO empathy for anyone except herself and her "darling" daughters, who are every bit as spiteful, two-faced, vindictive, and narcissistic as she is; worse even. What's worse, is that she's totally fooled my wife's parents into believing she's so wonderful and that my wife is white trash. And of course like the gullible fools they are, they lap that right up and continue to enable the narcissist and her family. We're done. After being harassed, slandered, and made an ass out of on social media by these hateful clowns, we told them all to go f*ck themselves and never set foot on our property again unless they desire an ass-whooping. These people are Advent Lutherans, and they are certifiably insane! My S-I-L actually has people believing that the Holy Spirit came over her on her way to work in rush hour traffic one day and "healed" her of a somewhat serious illness she had. Delusions of grandeur, much? More like "whacked in the head." Best thing I ever did was get away from these horrible people.....took me YEARS to get over their mutherfuggery, but I tell you the truth - best thing I ever did was get the hell away from their hateful bullsh*t.
Best thing to do with toxic individuals (or family) is to remove them from your life like the cancer they are.
