Guest,

Part of the problem may be that you are relying upon yourself to deliver your friend from this issue. The bible says that with man all things are impossible, but with God, all things are possible. So, it is not what we do in our own power, but allowing God to have control over the situation. Allow Him to shine through you and allow Him to use you wherever He can and He'll convict your friend of her sin (not only this but her need of a savior in general). You need to show your friend that you love her, even if you don't agree with her lifestyle. I know that is difficult. I've had friends who drink and, although they still do it, they know where I stand and why I stand there. And, so far, I have been respected. They don't typically drink around me. They know I don't approve--however, the Lord gave them a free will. He can show your friend her sin and I'm sure you've made a stand. Your friend will know that and hopefully she'll still respect you. However, turn your problem over to the Lord and who knows, maybe she will be saved soon and things will turn around for her.

Hope this helped.
