Is it a sign or just cold feet?

Everytime I think about going to law school in Virginia, my stomach turns into a solid knot and I can feel tears forming in my eyes. And I start to feel short of breath. I am petrified at the thought of going away by myself. And at the thought of failure. What if I can't do it? What if I hate it? What if I'm so lonely that I'm miserable? I don't want to turn into a boring "legal" person. I don't want to work in a boring law firm and wear boring suits. I want more out of my life. I want to be creative and fun. I know I'm getting caught up in "what ifs." I just want to make the right decision and not get bogged down in what other people think. I want to make sure this is my decision. Some of my options:

1. Go now to William & Mary
2. Wait a year, apply to SMU or defer my enrollment to W&M a year
3. Apply to Baylor Law to start in Spring 2006
4. don't go at all, keep my job, then apply for better pr jobs at an agency
5. Keep my job now, consider getting an MBA in marketing
6. Forget about everything, move to Mexico and be a bartender or move to Ireland and tend sheep
