As a parent, and someone with a few years of life experience: go ahead and cry for awhile and get it out of your system. It always hurts to be rejected, no matter for what or how old you are.
But then, let it go and move on. If you get into an ivy League or top school, great. If you don’t, it isn’t the end of the world. Life is what you make it. You don’t need a degree from a ‘top’ university to be a success in life. Success isn’t about the best job, or the most money, or the best (whatever), it is about being the best person you can be, loving others, giving back to your community and world, being a person of integrity, and so much more.
Good luck to you!
