Yay, you! Your history and process has some similarities to mine. I recall compassion for self being the major turning point in beginning to give up purging behaviors as well. We didn't want to do that to the child anymore. That too came from internalizing the compassion our own t had for us.
We also exercised compassion for those times when we couldn't help it... when we were not able to stop it from happening. Sometimes we could, sometimes we couldn't. Over time we were able to stop it more times than we couldn't.
Here's to your getting your control back from your ED!
