Thanks Tammy. A friend just sent me an article from the WW website (which is below in case anyone is interested) but it is still very discouraging and it's getting me depressed

I'm trying so hard and it's actually having a reverse effect! Anyway... here's the WW article:
Q: My husband and I have both noticed that on weeks when we exercise more, we tend to lose less weight on the scale than if we don't exercise as much. Why is this?
A: Stop the presses! Exercise is still your friend! First off, the scale only gives you a limited picture of what's happening in your body. It only tells you total body weight, but nothing about body composition.
You need to understand that exercise induces a series of normal biological changes. Habitual exercise promotes an increase in muscle enzymes that allows you to store carbohydrate more efficiently. This is a desirable effect since this muscle carbohydrate (called glycogen) allows you to exercise longer and harder without running out of fuel. Carbohydrate is very "hydrophilic" meaning it attracts water. So a little extra scale weight is a result of water binding to your muscle glycogen. Also, an exercise bout stimulates a slight increase in volume of plasma (the fluid portion of your blood) so this too may add a bit of weight.
Don't let this minor change in scale weight discourage you from exercise. Carry on with your fitness regimen and focus on your long-term goals. Over time, you will see a drop in body fat that will eventually be reflected on your bathroom scale.
