i don't think "being completely committed to recovery" is what is needed to be willing to go IP. i think what is needed, is a willingness to try to get to that point. i think being completely committed to recovery is where you might hope to be when you're ready to be discharged from IP.
i've struggled with ed's for a really long time as well. i hope you'll give IP and anything else that might help you a chance. you've been hurting with this for a long time, and you deserve some relief.
