Hi Jexa~

I'm sorry this is happening with your sister, and moreso, that you're so closely tied in your bonding with her. I know how you must be feeling, as I've been through similar.

I don't think you've mentioned your sister's age, (if you have, my apologies for my oversight).
My experience is with an older brother who, throughout our years, has proven to be a burden upon the family. It's escalated to the point where all in my family has excluded him, for the most part, due to his reluctancy of "straightening up". After all, we can only do so much for him. Continuing to give him money, provide him security when he blows it for himself, only prolongs what he needs to do for self.

I love my brother dearly, but there is only so much we can do for a loved one, especially if they don't/can't get help for selves.
And if you're not careful, that loved one can place you into situations that are not favorable for you.
You have to take care of you, first. And the best you can do is provide your sister what you have to offer without crossing your own boundaries for self.

I agree with NF. She needs to be clean before a dx can be made. And she will have to want this for herself, otherwise, unfortunately, it won't happen.

I hope the best for you and for your sister. Keep posting.
