How I've Combatted Codependency
Things I've done to combat codependency are:
Nights when he was gone - praying out loud and intentionally to hand him over to my higher power who I call God... and then focusing on what I needed to do for the night.
Counseling - free counseling through my church - they were not specialized in addiction, but taking this leap was crucial to my recovery. Trusting and applying their advice to my situation while knowing I had their backing was huge.
AlAnon
Joining a small group at my church to get out of isolation
Setting a boundary - if you use, you can't live here - and sticking to it. Kicking him out was the hardest thing I've ever done.
Very little contact while he was out of the house during that period of time
When family asked how/what AH was doing, I finally said, "ask him. Here's his new number." Stopped hiding him and covering up for him myself.
Stopped engaging in drug related confrontation. Stopped feeding into his victimization.
I'm sure there's more I'm not thinking of right now. Any more that y'all can contribute?
