Everything I have tried to do with my NPD sister has backfired with moslty her slandering about me to make me look bad, and her always playing the victium. We haven't seen each other in a deceade but suddenly she is sending me really nice letters I guess to reconnect. I don't know if I want to go there again. Sometimes the best thing you can do for you own mental healthy is stay away from people like that. Don't tell them anything, just quietly brush them off, you don't need to give them a reason or explaination because they will just twist yours words and use it against you.
