I appreciate that you mean well, and I understand wanting to help others with a difficulty that you have struggled with, but CAF’s content rules state that links to personal blogs or for promotional purposes are generally not permitted, and a blog on eating disorders doesn’t fall within the possible exception for Catholic-related resources.
Additionally, someone who has an eating disorder is facing a life-threatening condition and should be seeking help from medical and psychological professionals. I am not seeing anything on your blog stating this first, foremost and upfront.
