Hummm, this is an interesting question. I think I’ll take a different stance and say that it is okay to discuss anorexia in your essay especially since you are about to submit your essay. HOWEVER, your essay should be about GROWTH! Explain how you healed and/or perhaps how you positively affected your community through your struggles. For example, did you start a community support group? Increased mental health resources at your school? This is by no means mandatory, but these examples show how you have grown from your experiences. In addition, try not to have your essays be about the same topic so perhaps save this only for your common app. Colleges want to accept students who can cope with stress, who will be a good fit, and who will add to their community. As long as you show these, then you should be fine! Ik that you are literally about to submit your application and it must be stressful to hear these comments, but try to listen to everyone’s comments and see what you can do. You got this!
