Welcome
And I adore your avatar by the way, my fave creature in the universe.
I grew up a bit like you (raised by a plethora of addicts/alcoholics, bounced around house to house, ran off on my own at 14), and my heart hurts for you, because I remember being that hurt, scared, pissed off (etc) like it was yesterday. Hey, I'm also in Colorado
I'm glad you found 'us', this is a great place.
It might be helpful to you to educate yourself about alcoholism, there's a few good books out there. Have you ever been to an alanon/alateen meeting? They're super helpful for a lot of people.
Welcome!!
