Friend In Need,
You will be able to find a lot of great information here, resources, programs, meetings, etc. But find out how to help her? That is the age old question we all have faced and had to admit that probably there is not much of any you can do to help her,
Letting go of a loved one while they are still actively drinking/using is a very tough thing to do - I know I had to tap into the help of my Higher Power to be able to accomplish that.
If you are able, try to attend Al-Anon meetings, open AA meetings (to help understand the disease), read Al-Anon literature on detachment, enabling, and acceptance, these are some of my favorite comforts in recovery to know if my actions are the right thing for me.
Most of all, I hope that you take care of you, not to be unsympathetic of the suffering alcoholic, but you can't help someone that doesn't want help and most of the time we can't help our friends and family members anyway, because we are way to close to the situation.
Keep coming back, it works if you work it,
Rita
