I’ve been struggling with this same 10# for three months. It’s discouraging and depressing.
Plenty of people in my meeting are in the same boat. You’ve had a lot of things happen in your life in those three months.
One element in all the meetings is that they ask us to think of one small change we can make this week to promote weight loss. If you look at your plan materials, maybe you could find something simple you can do to help with your sense of control. Are you measuring food? If not, that might help. Do you get enough water? What about getting one (or two) more fruit and vegetable servings than you currently are?
