I'd just like to second the advice to head over to the Family and Friends forum and read, read, read. Don't miss the stickied items at the top of the page.
I'm willing to bet you'll soon start to see things in a new light.
I'd also like to recommend you look into Alanon for some real-world support. I find that using Alanon and SR both, for the strengths of each, is a great combo for me.
Welcome to SR!
