Weight loss support!!! Help me please!! Whats going on?!!?!?

Okay Okay, I was your average dieter, diet after fad diet, yo yo weight, always thinking about my weight feeling badly. Always saying "i'll diet tomorrow". Okay so after having a miscarriage when my husband and I had been trying over two years, I told myself that I would lose twenty pounds before TTC again. We miscarryed in october, and were told to weight two normal cycles anyway. So, you know what my new years resolution was. Except I went a step further, no yo yo's, watching what I eat and excercising. I also gave up soda. I was apprx. 80lbs overweight, since 1-1-08, I've lost 21lbs, and 31lbs since I was pregnant the first time. Woo hoo right? Well why don't I feel that way about it!! I eat apprx 1200-1500 cal a day, letting myself have two freebie meals a week (eating out with hubby/friends) And I feel so badly about myself, upset I'm not losing weight fast enough, (which I know is crazy!) The last few days I have to force myself to eat over 1000 cals. WHATS UP:?!
