As Dolly said, it has to be a lifestyle change and you need to persevere with it. I actually put on 8 kilos in the first few weeks of my lifestyle change due to my body adjusting, but have now lost 22kg. Most of that has been due to closely monitoring what I'm eating and doing extra exercise.
We all understand how you must be feeling - I dare say most of us have felt similar at some point. It's one of those things that you have to be mentally prepared for and comitted to long term.
I know it can seem overwhelming too, but if you take it one step and one small goal at a time, you will get there in the end.
How about just start by picking an exercise plan - say get off the bus a few blocks early and walk the rest of the way. Then you can go up from there.
