Hang in there. I just wanted to say that I think many of us have our doubts about if this will work. I have to 'make' myself positive every day. Every day. Log your food, do what you can and then do one small thing more. Make one more healthy choice. Say no to one more poor choice. You don't have to do it all tomorrow and you don't have to do it alone.
This is a great board when you have those doubts and the moderator is top notch. Take this journey slowly and come back and post tomorrow about the positive change you made!
