Discouraged.

According to my Calorie count app, I should have lost 4 pounds in the past two weeks.
Instead I have lost none. And I have no energy. The caffeine I need to get through my day is making me jittery and if I restrict any more I'm certain to binge. Net Calories have been right around 900 each day (some days a little more, some days a little less) I know if I consistently consume under 700 for too many days I binge so I'm trying to avoid that, but honestly, how the fuck am I supposed to lose any more weight like this? I'm not skinny. There's no reason this should be so difficult. Aren't you supposed to shed pounds easier if you're fatter? I'm getting so frustrated.
