I can understand your frustration. I cannot answer your question but I can tell you about my older sister that I believe is narcissistic. She has always been jealous of me as I am the youngest girl but I did witness as a child she used to punch me in the stomach make fun of me and belittle me in front of other family members. Her husband divorced her a few years ago, he found a real women that didn't abuse him. She used to hit him, flipped him over in a wheel chair when he had broke his leg and was a total drunk. She dragged our whole family into her drinking bindges. Every Friday and Saturday it was the place to go and get drunk. My poor mother lost her baby brother when he was 40 and she started drinking right with us. My dad passed away in 05 and she has now taken his place. I don't want my mom to drink because of her medication. My sister bought her a bottle for her birthday knowing the Dr.s don't want her to. I told my mother if my sister bought her a bottle I would throw it down the kitchen sink. I believe she told my sister and the last time I called my mother she yelled at me and told me not to call her anymore. It has been over a week and GOD it HURTS so bad. I can only tell you do not tell your sister anything intimate about yourself, keep your business to yourself. If she goes into a fit of rage because life isn't going the way she thinks it should try to talk about a nice childhood memory you had with her and your mom. My sister is no longer an alcoholic but she is a dry drunk which is worse. She never got the help to understand herself and now she thinks she is the queen of knowledge. WRONG! She is also I heard, wanting to tell my fiancee' something about me to make us break up. So see, she wants total control of me. My Psychiatrist told me to stay away from her that she is crazy. Love your mother YOUR WAY and let her know it.
