Welcome back
I really empathize with your frustrations with your scale, but I have one little question about your goal: what IS your goal?
Is it a lower scale number or fat loss? Because the two are not always the same.
Remember that while the scale is a wonderful measure of how much the planet is pulling your body in towards it's center, it's only an indirect and often inaccurate measure of how much fat you have. Measurements, how clothes fit, and pictures are all more accurate measures of fat loss than the scale is.
