Are you sure you're eating enough calories? I'm only asking because your food budget is less than mine by quite a lot, and you're a lot more active than I am! That might have something to do with the lack of loss, but if you've already figured it out and it's the right level for ya, disregard that.
*hugs* I know it's frustrating, but hang in there & keep at it!
