Welcome!
A great place to start is the "stickies" at the top of the forum. When we have had a really helpful thread or topic it gets stickied so it is easy to find and refer to others.
I second alanon. Changed my life and gave me a "new pair of glasses" to look through and help me find my way out of the family disease of addiction.
I also found a great family therapist who knew addiction and he was simply amazing... still love that man for his tremendous insight, vision, empathy and understanding.
Finding support, resources and just knowing that you are not alone will make every day easier! I am an oldtimer...been around these parts for 4 years now.... was lost, confused and hurting just like you when I wandered upon this site!
