"Oh, great, reality."
Tomorrow morning, answer that (which I believe to be your Addictive Voice trying to give you ammunition for your next drink.) I would snipe back with, "Yeah, yay! I woke up! Another fresh start today!" or whatever positive thought you can use to magic-away that AV.
I had gotten into such a depressive pattern of thinking that it was a couple months before I was consistent in my back-talk to that. IT wanted to bring me down. I learned to win the argument with myself.
You'll feel better than this. Trust the process, and work to stop beating yourself up over the relationship. Some people are meant to come, be a teacher, and go. That was her role. There was a lesson here for her, too.
Blessings.
