I think you had some assumptions before you posted this thread, and you want people to echo your feelings. To tell you what you think is correct, that Ivies purely didn’t accept you because it was this year. But a lot of people here told you the truth, from their experiences and others and I guess you didn’t want to hear it.
Don’t reapply to the same colleges. Take a gap year if you’d like, but plan out what you’re going to do. Continue at WashU, work your butt off and get a transfer. Or go to WashU, and realize that they may be the one for you. Whatever you choose, it’s up to you. Just don’t take out your anger and frustration on the kind people here who’s giving you advice.
