When I look my BMI/Activity Level up on a calorie calculator, most of them say I need at least 2000 a day to maintain -- and I am 2 inches shorter than you are. More food, my dear...shovel in some almonds.

While going to see your doctor is not a bad idea, I wouldn't sweat it too much... Often after weight loss people get light-headed because of the drop in their blood pressure. It takes a while to compensate.
