Hi - thanks for sharing your story. There will be lots of advice available for you here at SR. It may be useful to look at the friends and family sub-forum though...
Friends and Family of Alcoholics - SoberRecovery : Alcoholism Drug Addiction Help and Information
I think it's definitely worth looking into AlAnon and AlaTeen for some support as well. It's time to start living life to the full, and there needs to be some recovery from your experiences to help bring that to fruition.

Good luck. There is support and hope out there for you.
