I hope you didn't top out your calories at around 900! That's too few, even if you're petite with a tiny frame. If you starve yourself, you're going to lose muscle mass and slow down your metabolism. Please be careful.
I can relate to wanting to hit your goal weight ASAP, but I have learned the hard way that whatever you do to get yourself into shape is what you have to do to stay in shape, and if you don't intend to keep up a hardcore diet and exercise regimen forever, you'd be better off with a moderate diet and exercise plan (and slower weight loss) that's sustainable.
