Have you browsed around the Community tabs on MyFitnessPal yet? There are so many resources for support around people who are going through issues just like yours--from setbacks like disease and injury, portion control, tips on practically changing the way you eat, etc. I was just reading through some of the blogs, and they are so creative and inspiring. This one particularly caught my eye: http://www.myfitnesspal.com/blog/dsjohndrow/view/1300-days-and-counting-721989

Please post any Blogs or Groups you find particularly useful here.
