In your post you said you were concerned about disclosing your former eating disorder. Although I'm not and admissions councilor, I would advise you to actually mention why you didn't perform your best at Nova. I think you have a perfectly understandable situation and I seriously doubt any adcomm would hold an illness against you, especially since you've done such a remarkable job recovering and earning a high GPA at American. Also you should feel confident about your credentials for LS, a mid 3 GPA and like a 169 would make you all but a lock at most of the schools you mentioned (providing your essays, PS, and extras are decent) and it would give you pretty good odds at UVa and G-town. All in all I say disclose all and be confident.
Why would an eating disorder cause you to do bad in school?
