You are already on the road to healing by understanding and accepting that you want to change something in your life for the better. We don't always have to have the answer of how we are gong to get there, but just knowing that we want to be better, healthier, happier etc is all it takes to get the momentum and energy flowing in the right direction.

It sounds like your home environment might not be the best for trying to reduce exposure to alcohol, but that's okay, take each day as it comes, don't worry too much about the future, just focus on the now and try to enjoy each day as much as possible, no judgement, no criticism, just love yourself and know you have the strength to do anything you want to. Belief is one of the most powerful energies we have for change, so just believe, really feel it in your heart that you can do this, find your joy and connect with your amazing, wonderful and talented true self, expand your possibilities and listen for clues everyday, the universe will always answer. :)
