Hmmm... I'm not sure of exactly when and how people are notified, but most of our students know the dates that results will be available on the various UC websites. I'd guess that you'll know a lot more in a couple weeks, so don't worry so much.
And you need to be confident that you'll be happy no matter where you end up. Or perhaps that the highest-ranked school isn't necessarily the best. We had a student last year get into UCSD, hate it, and then transfer to lower-ranked UC. She's much happier now. So it's really hard to tell how you'll feel about where you go.
Just relax. There's honestly no point in working youself up too much. Trust me, I see this every year. The next few months of your life will be very exciting with all the changes, and you should enjoy every minute. It's really a very special time of life, in my opinion.
