Confidence question? help please!?

i know this is stupid, but i really do need some answers... im not looking for compliments and im not bragging or anything. but i have been told by everyone that i dont see myself right. everyone tells me how pretty i am, and i do have guys interested in me.. but what everyone doesnt know is, i hate my body!! i am so insecure about it and im sick of it. i weigh 135 and am 5'6.. average i guess. but im so tired of hating body.. my face is okay, but i hate my body! i want to be able to prance around in a mini bikini like all the other girls my age. (im 18). i work out a lot, its my whole life, and i eat healthy..but my question is, how do i get over this? what do you do when you lack confidence? and what do you suggest i do? im tired of hating myself. i want to be comfortable in my own skin. thank you so much in advance
