On behalf of everyone on the forum, I'll just go ahead and say it...
QUIT STRESSING. You're in. 🙂 The mistakes are minimal and unintentional and it's clear they're not lies you were telling in order to ramp up your application. If you're that concerned, once you choose where you'll matriculate, contact someone there and just let them know there were a few minor errors and that you wanted to be forthright and make sure your application was completely honest. I can nearly guarantee they'll just say, "Ok thanks!" and delete your e-mail. Congrats on multiple acceptances this early on. Now rest easy and pray for the rest of the stressed out crazies on here that are still waiting to even get an interview 😛
