Speak Up

My sister is addicted to meth. She is the kind of person that meth loves....someone who has everything to lose. She was my best friend. The picture is of the two who are the most deeply hurt. She has a 7 year old daughter and a 4 year old son that she hasn't come home to since Friday. This month is the one year anniversary of her involuntary commitment when she refused rehab last year. She was released last March, and stayed sober from meth. She instead drank excessively and smoked pot and completely turned against everyone who cares about her. She and her horrible BF broke up for good last Friday and she immediately spiraled down and has relapsed severely. I am desperately seeking advice from non-users and those with meth experience. She says I am dead to her. How am I supposed to keep her from feeling abandoned and like I gave up on her, even though I hate her for what she has done to my niece and nephew? I do love her, but it's the girl I used to know. It all feels like a sad dream that has no beginning and no end. Meth has made itself the center of all of my families conversations. Meth is selfish and it lies. No one escapes unscathed. But I cannot let meth win. For those of you that use, what would you want your sister to do to help?
