Get off your butt and work out! Go running, lift weights, do something. Oh, and don't forget to get rid of the junk food. All the exercising in the world is not going to help if you're still eating the wrong things.
If your not completely in control of yourself you won't succeed to where you say you wanna be. You really wanna lose weight, start to workout and see how long you last, if you don't make it week mark, you don't want it bad enough! Keep fighting!!!!
