If there is a possibility of surrounding her with family and friends that care about her, your family could do somewhat of an intervention. Getting a support system established for her is vital in recovery. I'm not sure how far apart the two of you live, but bringing her closer to family would be number one on the list, if possible. If impossible to do so, there are some intervention actions you can still do to "wake her up". Remember, when dealing with an addict (which I have had friends walk this same road), most of the time there's an underlying reason behind their addiction and if that root problem can be addressed, its easier to deal with the addiction. I hope this helps and best of luck to you all!
