if you ralized that you dont really have anthing to lose and its just a problem of stress, go see a psycologist
but if you really feel like you need to diet try weight watchers. its a really good diet. it allows you to eat all types of food even junk but in limited amounts. i lost 20 lbs in a month on weight watchers but i really stuck to it. if you really want to lose weight you cant cheat. ever.
