Someone please help, need to lose weight.. feel depressed?

Well, I'm not sure what Weetabix is. Probably a British thing. But it sounds like a lot of carbs. Cut back on the bread, pasta and coke and you should be okay. If you are exercising as much as you say you are and not losing weight, then you must be eating 5 lbs of lard a day. Talk to a doctor about your diet and reevaluate what you are eating.
