The one thing I know for sure about alcoholism is that real emotions are avoided and distorted with the alcohol. It's a method of escape.
If she can find her way back to her real emotions, then process them without reaching for the bottle to escape, she stands a good chance at recovery.
Those real emotions are attached to her very real demons. Only she knows what those demons are; nobody else can even see them (unless something like she shares them with a psychologist). They are hers alone to go to war with.
We're left standing on the sidelines watching the battle. We can't fight it for them.
