Welcome back! There are lots of us with that story, and what's important is that you are back and ready to be healthy again. Compared to home, office jobs can be deadly for trying to eat healthy--they're full of office lunches and birthday parties and happy hour with margaritas. But as time goes on, more and more people are understanding that sugar and carbs are bad for us, and it gets much easier to just say "Oh, I can't have sugar," or "Oh, I'm so sorry, but I can't eat that--health stuff, you know..." So, there's less weird questioning and push-back from co-workers.
