Is it normal to feel like this after getting accepted to college?

I just got accepted to college, got my welcome package, everything is set. I tend to over think everything and I'm getting freaked out and scared that I'm doing the wrong thing. I know I'm going to love what I'm taking (web animation and design) and the job aspects are great in my area. is it normal to get scared but at the same time excited to go? I've had this problem for a while, I dropped out of my last college course because of this last time and I really don't want to do that again. can I do anything to get over that feeling? like does meditation work at all??
