I agree with SwimGirl, you lost 30lbs, that is great.
As for the new scale, your weight is what it is. Now time to move forward, you know what you need to do, just get back on track, you can do it, and that new scale will also show you what you want to see.
As a side note, I found getting on the scale daily was making me crazy, so I only step on the scale once a week, those daily up and downs, can make me go right to the naughty stuff.
Continued Success-you are doing Great
