I wouldn't consider it my job to handle her as I am a separate individual living my life the way I see fit.

How old are both of you? Age will make a difference in how to answer.

Indiana - Now I can relate. I've a female sibling 3 years older (66). She's a phychopath. She's borrowed from the parents (stollen really, because she's never repaid a penny), lied, used, manipulated people, bankrupted her husband, written bad checks on her own daughters checking acc., and to top everything off, she manipulated the mother into leaving everything, EVERYTHING to her and publicly dis-owning me. I've been the one who looked after the mother when the father died but, hey, that doen't count. She burned and destroyed everything that was my personal property, (school pictures, letters ets) so I have nothing of my childhood. In the end, I had no choice but to cut her out of my life. That was 12 years ago, and it was the best thing I could have done for myself. I'm finally at peace and can live a normal life without being on edge wondering what lie she will tell about me now. I would never tell anyone what to do. All I can do, is relate my own experience with the same kind of person. It's a hard choice to make but you MUST think about your own well being. My therapist & pastor once said to me, the Bible doesn't say you must love your parents or siblings. It says to 'respect' them. That's a whole different thing. I can respect her for being a person, but I would never go out of my way to make friends with her, let alone love her. I wish you much heart peace. You have my deepest sympathy.

You are designed to be a caring and compassionate individual. I assume you are female; you can't help it, and you wonder why she appears to be otherwise. We do that. We do what we're supposed to do and expect others to do the same, and then wonder why we get hurt. The answer is "detachment". Separate your sister from her disease. She is a person and is trying to address her own feelings in her own way; we all do strange things to protect our feelings. Do not judge her heart. Simply do not feed in to her illness. Love her but put yourself first. As selfish as that sounds we cannot help others if we are not well ourselves, and having a troubled loved one will drag us down. I hope this helps.
