I was a senior applying for colleges last year, and I have to say I took it all pretty badly myself. I applied to about 16 schools (that is, counting the UC system as one entity since they have the same application), and from all of those schools, I was accepted to perhaps about five of them. My story had a happy ending because one of those five schools I was accepted to was actually my dream school, but I also experienced the immense grief and disappointment your D is facing now since my acceptance to my dream school was the last one I received.
The comparison of ‘Oh, well that person is famous but they didn’t go to an Ivy League’ always felt weak to me back when I was a senior because in my head I could list any number of other famous individuals who DID go to a prestigious college. Any time my mother would tell me “Oh, Steve Jobs went to some no-name college and dropped out”, I would counter and say, “Well, Oppenheimer, James McNerney (at one point CEO of Boeing), and any number of U.S. presidents went to Harvard.”
I think what actually helped me along in my disappointment was something like this:
No matter how prestigious your school is, there comes a time in your college experience, during your day-to-day activities, that you realize you’re not even really thinking about your school’s prestige at all. When I’m interacting with my roommates/floormates in the dorm, or talking to my professor at his/her office hours, I’m not constantly thinking, “Cool, I enjoy hanging out with my floormates because my school is prestigious!” or “I only want to talk to my professor because he teaches at a prestigious school!”
In the same way that high school should have been both an academic and a social center for your kid, so will be college. Your child may have chosen to go to a tough or competitive high school for its academic merit, yes, but once they actually entered school, the whole package was a lot more than just the grades they aimed for. In fact, they’ll probably remember best the friends they made, the teachers they bonded with, and the subjects they found the most inspiring. All of these things- friendships, academic inspiration, etc.- can happen at any high school and at any university if you approach it from the right angle.
I wish your daughter the best of luck! Allow for her to be disappointed and discouraged, because that is completely normal, but also help her to start moving on.
