There is no sweepstakes on trouble. It doesn’t matter in the least whether your problems with eating are better or worse than other people’s. You were diagnosed with an eating disorder 3 years ago. Period. To your credit, you had the courage and the perseverence to get treatment. It sounds like it was largely successful. You still don’t have an absolutely healthy relationship with food but you are getting there. You are not endangering your life or health anymore and you’ve developed other ways to handle anxiety. Good for you!
Rather than being in an argument about diagnosis, I think it would be more helpful for you to give yourself credit for how far you’ve come and then refocus your treatment. i worry that your identity has become somewhat tied up with having the diagnosis. I’d like you to instead be redefining yourself as a person who has done good therapeutic work and who has developed positive ways to manage stress. Can treatment now focus on building your self-esteem and self-confidence so that you can truly put the eating disorder behind you?
I suggest that you talk to your therapist about setting treatment goals for the present and near future and that you leave the past where it belongs — in the past. Of course you deserve treatment. But at this point treatment may take a new direction so that you can eventually terminate therapy.
I wish you well.
