I'm glad my sister found the right path too!! I hope your sister grows out of this stage too!! At the end of the day, we can't live their lives for them, all we really can do is try offer guidance, but you can also only do so much, and really, you can't sacrifice your own life if people don't want help!

All you can really do is be there if she decides to come to you for help, and if she does, you take that chance and get her right, that's what I did, and that's all you can do!
