That's a very sad and very dangerous situation for your daughter.
You can't change what happened in the past. But, you did the right thing by refusing to move near her and by refusing to be involved. What she is planning to do sounds very dangerous. I'm sure you're very worried about her, but she has to make the choice to change her life.
Get rid of the alcohol you bought and get back on track. You need to continue to move forward with your life. You've come a long way and you don't want to lose what you've worked for, ie. school, job. Show your daughter, by your example, that you are leading a sober life.
