The odds are high that you're going to a "safety" school, and the odds are very high you're not going to your "dream" school. That's very normal; it has a lot more to do with the economics and logistics of admissions than you as a person. Just ask yourself how many times you've heard some sad person say "my problems all began when I graduated from a university that wasn't my dream school." You're going to be fine.
But there's a way to make sure you're going to be better than fine, but great. And that's to remind yourself that whatever it is you were looking for is available where you're going.
When you strip away the names and specifics but instead focus on the qualities that you were looking for, you can almost certainly find those qualities at the school you're going to attend.
