Help for cellulite!!?

i am 19 years old.. 5'10 and 127 pounds. yet i have cellulite. mostly on the back of one of my legs.. and its really affected my self esteem..i will never again wear a bikini or be seen in my underwear. Its not just small "orange peel" dimples.. its noticeable chunks of fat clumped together all the way down the back of my leg below my . like "rippling" I don't have money to get a cellulite treatment at a spa.. i have bought creams and maged the area but i get lazy and stop after a week or two. i bought a scrub brush for the shower to help with drainage of the area.. does anyone know what else i can do! i am desperate!
