"You ruined my life!" is what an alcoholic (or anyone, really) says when he doesn't want to face the fact that he ruined his own life.
Delete the message. You're responsible for your life; your dad is responsible for his. As a mom, I cannot imagine saying that to any of my children, but I know the sting of hearing a milder version of that from my mom.
It hurts, but don't let it destroy you, and don't drink over it. You're worth more than that.
