Well, first of all let me say that I will be praying for you and your family. I admit that I have no experience with unruly teenagers, mine is only a toddler, but I was once, not too long ago, a teenager too. My suggestion is that you spend lots of quality time with your daughter. My experience with siblings with drinking problems are that they drink mostly because they are insecure about something. It is your job as her mother to find out the underlying cause and nip it in the bud! Whether she responds to you alone or if she needs counseling, get her help because it will only get worse.
