I see you are an alcoholic (recovered?) too and started at 18-45.
Do you think she is learning that alcohol may solve some of her problems and once blasted, her anger towards you being an alcoholic is coming out? I would imagine this child grew up watching you drink every day of her young life?
My statements above still stand. You need to let her deal with these issues. No one brought you to recovery yourself. You did that for you. This will be the same thing but will take a very long time to come to a head if you become her enabler.
