If anything, you've got to look on this experience, even though this is going to take alot - as a positive one. Now this may sound slightly insensitive of me, when you have no confidence, but you've got to start showing people who you really are. Show them how bullying has made you stronger, and more determined to fufil your goals and ambitions, that they probably never will. Believe me, I was bullied harrassed at 18! I thought that kind of immature behaviour didn't exist then. But by god, I showed them what for. And now they're the one's that are paying for what they did, not just to me but to others too.
So, my advice is - don't forget what happened, as that won't happen so easily, but remember you are more confident now, you're stronger, and you're better for it. So live that life!
