Can doing this make me lose weight!?

ok so i am only 17, almost 18, year old girl. all my life i have been chubby. dont get me wrong i am NOT obese or anything near that, but i have saddlebags and a little stomache and bigger thighs. it depresses me so much... i work out, i eat pretty good, yet i have never dropped weight. but all my life i have for the most part NEVER drank the amount of water i should, if much of any water at all. know that i know the importance of it i am trying o drink the amount i need, could drinking water make or help me drop the ten or so pounds????
