You don't have to be ashamed! At least you're getting back on track, right?
I first joined 3FC back in 2006. I think I was somewhere in the 140s or 150s. I lost weight, but then over time, I stopped keeping track and gained a fair amount of weight. I all but forgot about 3FC.
I happened to stumble upon 3FC back in May of 2010, and I was glad I did! I was out of shape, getting towards my highest weight again, and needed accountability to get back on track.
It's OK! We all go through periods where we fall off the wagon. What counts is what we do when we fall -- stay down? Or get up and keep high-steppin'?
Anyway, welcome back! I wish you tons of success on your weight loss journey.
