Just as a contrast - I can remember (as a rather distant past - has it only been 5 years?) hating myself all the time for being so fat. My mind was a very uncomfortable place with my inner voice always telling me how awful I was. Ouch!
It slowed down somewhere during Step 3 and went away without my even noticing, helped along by some of the classes such as 'Fat Terror' and 'The Obesity Myth'. But mostly, helped by just doing the program and healing my biochemistry. And now - no more of that demeaning, accusatory voice berating myself all the time. Freedom!!
