<p>I think it is hard to answer this without knowing what you mean by “mental illness,” but I realize the demands of anonymity prevent you from offering more details.</p>
<p>If your illness is sufficiently severe to require withdrawal from school, you can either finish applications now so that you have the option of going in the fall, or you can wait and do applications for spring or fall 2013. I think that depends on whether you are feeling up to doing the applications, essays, getting the recommendations and so on.</p>
<p>You could finish high school at home, via tutoring or some other method.m (One of my kids had a chronic illness in high school, and teacher filled out sheets every day for her with what was done in class, homework, notes, any tests or quizzes, grades missing, and so on. It worked great, but she did the work completely on her own.)</p>
<p>You could finish high school in other ways. Dual enrollment at a community college, extension or continuing ed or online courses at other colleges/universities; you can get a GED (and if you are waiting to apply, you could get a head start by taking classes after the GED if you like); there are also schools that will compile all your classes and activities and grant a diploma from afar, based on requirements that are sufficiently rigorous (not diploma mills). There are also schools affiliated with mental health facilities, that might serve your purpose.</p>
<p>There seem to be quite a few students at top colleges with mental health issues. Many are revealed after admission. You or your guidance counselor may have to present some sort of explanation for withdrawal from school. One advantage to applying next fall would be that you could present the problem as being treated, and would be seen as having overcome an obstacle that is difficult. If you did well in classes/jobs after treatment, that would help a lot. (This is what Harvard asks of students who go on leave for mental health reasons, after matriculating, in order for them to return.)</p>
<p>I wonder why you want to go to an Ivy type school. There are many schools that would be available to you, and I would encourage you to look at many options. Not that you cannot get in, or handle the work, just that there are so many wonderful schools out there “beyond the Ivies.” </p>
<p>In any case, getting into Harvard or Yale is not a priority at the moment. Do what you need to get healthy, then you will have more perspective on your future. Things will work out in many places: the important thing is to get well, or, perhaps more appropriately, get a handle on living with the illness and managing it.</p>
