I'm going to check out those books. Very recently discovered that I have codependent tendencies, could be from being raised in an alc home too.
Anyway, one thing in addition to doing what everyone else here has said, is to keep reminding myself that I can't change his outcome. That all my worrying in the world won't make him call or show up any sooner.
So, I may as well use that time and anxiety to create a project or paint or go running or anything else to get it out of me.
Sorry you're feeling like that, definitely not a good feeling to live with.
