Teens aren't insane, I'm not one yet either, though. My uncles are, but they actually have sense to do their responsibilities. :) I have braces! It really hurts the 1st week like its never going to go away but it will.
Yes, it's not bad. I had to get 4 teeth pulled out because it was overcrowding, you're really lucky! It really feel likes your tooth are going to fall out any time but it won't. Don't be so nervous, it will be numb but it won't be as awful.
