I'm a senior with ADHD in the midst of applying ED to Cornell. I was diagnosed with it in Kindergarten, so I've learned to cope with it for the most part, but it was enough of a struggle that it has made me want to become a psychologist or psychiatrist so I can help other people to overcome their problems or disorders as well. I have a GPA of 3.73 unweighted and a 2240 on the SAT's and I'm an officer of 3 clubs, but my ADHD can still sometimes make my work take much longer for me to do. If I were to disclose that I have ADHD in my essay for Cornell, it wouldn't be to explain shortfallings, but would instead be to explain a personal reason why I really want to be a psych major. My parents think I shouldn't disclose because ADHD can be seen as a disability and a huge negative, but every guidance counselor at my school thinks I should disclose given my personal reasons and I think so too, but I'm still uncertain.
Should I disclose, or would a competitive school like Cornell look at ADHD as a disadvantage?
