Howdy! (: i need some help../:?

okay, so im a 15 year old girl, and im very comfortable with my body, most of the time. im not in the best shape, and i know i could look a lot better.. i just dont know how. i hate being one of the bigger girls on my team.. (imma cheerleader) i know your supposed to eat healthier nad excersise, i just hate asking people for help excpecially my parents. i weigh 188 pounds, and im 5'4" i dont look lik ei weigh that much, but i do. and my boyfriend always kids around about my jiggle and stuff.. but sometimes i take it to heart and i feel like crying thinking im not good enough. i always put on a smile when someone jokes around about my jiggle, but it hurts. i have limited excersising tools. i have weights, outside to run, wii fit, and just dance one and two.. i just need someone to make me an excersise program that i will follow everyday, nad i will work on my eating. i really wanna weigh 150 by august..
