One thing that resonated and stuck with me was the idea of externalizing the behavior. I think much of the shame and embarrassment and self-stigma imposed is due to internal thinking that WE are causing this damage.
If you can give up ownership of your BFRB to the "Monster" that needs to be tamed, it becomes easier to challenge this disorder.
Here's a few ways to begin to look at your BFRB as the "Monster":
First, name it, to tame it! By giving your "monster" a name, you are detaching yourself from it. You need to remember that these behaviors are because our "fight or flight" response system has gone awry -- YOU are not the "problem."
Next, draw it! This will help you give your BFRB human qualities and help you visualize something in your mind to challenge vs. this elusive and invisible disorder. Drawing is also cathartic art therapy exercise.
Third, talk to it! Instead of responding to urges with berating negative self-speak, I've found that challenging the monster in my mind, with questions like "That's all you got?!" squashes the urges.
You can then enlist your support circle and join forces to help you keep the BFRB monster away.
