That's what silly girls do.

You do not indulge in self-pity, you complete idiot of a person. You just don't, no matter how much they tell you that you suck and that you will never be one of the smarter ones there. No matter how much they look down on you. 
You do not sit there and sympathies yourself because that is what those silly girls do. To get out of this hell hole, you will just have prove yourself again. You use those people that laughed at you to your benefit, and you just have to suck it up when you feel like crap. 
You go back to the bitch you were because it is the only way out. You tried being that little saint that embraced everyone, but it did not work out. So if playing the angel was clearly the wrong move, you take a step back and play otherwise.
