I’m sorry you find yourself in this situation. You have good stats, so, with nothing to go on but a hunch, I suspect your essay or your teacher recs were not what you expected them to be. Could also be that your unweighted GPA was a little low. I also don’t see any safeties. Read this, as you might recognize something that could help you figure out what might have happened:

I do not agree with post #2. In your shoes, I would take a gap year and try again next year, but with a more balanced list. You should consider schools that will offer you merit aid. Look at some LACs, maybe the South, PNW or Midwest.
The NACAC list on May 1 will have all the colleges that still have places available for this fall, but who have miscalculated yield for whatever reason, or maybe have built new dorms, etc…
I suspect you can get off a waitlist at one of the UCs. Email them, tell one of them they are your top choice and you will attend if accepted. You can also try that for Lehigh, but there won’t be any financial aid at that point, most likely. Good luck.
