I lived with two ACA members growing up, and though I attend some AA meetings they are open only.
I am in recovery from an eating disorder however.
The reason I am writing is that I am experiencing similar exhaustion. I talked with my therapist about it and she let me see that healing is hard work and exhausting. We are making new brain pathways, and at least for me I am trying to get out of the crazy hamster wheel of do, do, do that in my codependant ways I am so familiar with. I imagine it like my framwork/structure being tilted like the leaning tower of Pisa, and me tearing that down and building it again. I know that is good for me, but to let go of stuff that I have grown up with can be anxiety provoking, and building a healthy framework takes a lot too.
It helped me to see that maybe for me this is part of the process.
