I too am happy to know you have all this support.

Just remember be her rock. Where she swerves all over the road, drive along her in a straight line ready to help her if she crashes. If she does remember it's not your fault, and don't let her blame you for it. Don't be confrontational just let her make her choices and follow her actions. Let her see the damage she is doing to both her families and herself on her own.

Only until she sees this will she be able to start healing. Good luck.
