I must agree with garden! Carbs doesn't elevate happiness! Healthy foods would. I never thought about having a better approach in regards to food, and I will remember this. Thank you, southern! Anyway, while I was depressed though, I filled up on carbs (Cheerios, other cereals, and chocolate!) and orange juice (which just added to the acid in my stomach from being stressed.), so I'm guessing acidic drinks with Vitamin C isn't the best thing to have..
Also, stay away from gum! I'm sorry but it doesn't help at all. It never helped me, especially the ones that weren't sugar free because it made you aware that sugar and extra calories were coming in! So, gum, sugar-free or not, isn't a good idea to have.

I also like adriano's approach; it sounds like a good diet as long as it's balanced.

ps: I'll be even more honest here. I'm not sure if excercise does much! I mean, it grows awareness on how many cals are being lost, so maybe that awareness will drive you to excercise more and more? Maybe have a diet first, and when you're starting to feel better, go out for that jog.

Best of luck hun!
