You Mean To Tell Me Working Out Really Works?

Happy days are here again! Since last week, I've lost 4.3 pounds! Although I certainly didn't eat the best at some points, I still did ok and worked out a fair amount.  But I still need to figure out a substitute for food when I'm feeling anxious, sad, upset, or that the sky is blue (I used to have a tendency to do that a lot!)  Suggestions are welcome!
