I'm sorry you're having trouble starting back up. It is so hard to break the cycle. There were times when I was on the program before I had my daughter that I would go through what you are now. In the end, I just bypassed the yellow & blue menus and went straight to green. I know you're not supposed to, but it's what worked for me.
My thoughts are to just bite the bullet in the morning, take the measurements and weigh yourself. Maybe it's that kind of reality check that will help motivate you.
Hope to see you around here more often!
