Good morning from my part of the world, ISO! The stick shift analogy is a good one.
It sounds like you're doing well. Keep on with your coping strategies and taking care of you!
I continue to work on my recovery. Though my son is past the crises of his teen days, now an adult, again living at home with his dad and me, I am ever watchful of myself and my codependent MO. Fortunately, my son is working steady, we don't see each other much, and "yesterday's" drama is mostly gone. IMO, it adds challenge to the goal of recovery as a codie when the addict is a dependent child (as I'm sure you well know and are experiencing).
It's good to hear from you. Your post is encouraging and positive. Wishes for continued strength to you!
