I am feeling really self conscious about my stomach...?

I am a skinny person, except my stomach. It sticks out, and I feel like I have to wear loose clothes all the time, and I want to show off my body more, because I really do like the rest of my body. School starts soon, and I am trying to loose my stomach fat. Anyone have any experience on loosing stomach fat, and in, maybe, a week and a half? I want to be able to wear a bikini, dammit! ;)
