Progress but not in all places.

So, I have been in Sem since Dec, and I have lost 40lbs so far. I have 30 to go. I’m supper proud of myself for sticking to it, but, no matter how well I eat, my stomach will not shrink. It’s like it’s fighting me all the way. They say it’s the last to go, but it’s really starting to discourage me! Ugh.
