well most is already said.. you are under eating. I think you have slowed down your metabolism from eating at such a low cal intake for too long and your body is thinking your starving it. So, if I was your size I would be eating
at least 3000 cals a day for 2 weeks and then see where you are at. Let your body know you love it..
