Hi, I can chime in and say that shooting to lose 2 pounds a week is difficult when you are "height challenged;" I am, too. Also, the closer you get to your goal, the harder it is to get the deficit that you need. It does sound, though, that you're in a big ol' plateau. Be patient, change something up (type of exercise, your percentages of fat, protein, carbs...) just to try to "wake up" your metabolism. Are you doing any weight training? That would be an excellent addition if you aren't doing it already.
And now that you don't have to be perfect, you can be good.
