Is she an adult? If so, she must be allowed to be responsible for herself, for her actions.
If she truly wants recovery she will seek it on her own and follow through, for her, not you, not anyone else.
Trying to solve her problems for her is not the answer, in fact, in most cases
enabling only delays recovery.
As hard as it may be, she must fall to her knees before she can have a chance to stand back up...and she must do it on her own.
You are in my prayers.
