Lucy, I’m not sure what you mean by accepting your weight, so don’t have an answer for you on that one.
In Week 1, one of the Solutions I put forward is to remind yourself of your non-weight motivation any time your attention gets drawn to the issue of weight and weight loss. It looks like you’ve got plenty of non-weight motivation in terms of recovering your health. This is excellent.
It seems your major obstacle in moving forward with that is your sense of prohibition. What will make all the difference for you is to deal with that by declaring and asserting your freedom of choice.
