I know it's hard to stay calm, but don't sweat it!!! Even if the worst happens, and you don't get into any of them, you might even think about the rejections as an opportunity—you get a whole year to narrow/strengthen your interests, and to improve your applications with all the knowledge you've gained from this cycle.
I was roundly rejected last year, and this year I'm getting into my dream schools. Just be patient and confident that this is what you want with your career, and I have no doubt that you'll make it happen
