115 pounds... fat? what?

So last year when i went to the doctor she told me i'm 115 pounds... and overweight..? I am 5 feet tall and have been eating crap my whole life. I LOVE ALL food. Its kind of a problem.  I hope people comment and call me fat and whatever because I know Im overweight and want to at the very least inspire change in some girls my age. Im trying to be as realistic as possible. I know change wont happen overnight... but can I just tell you, I actually feel less bloating in my stomach already.. after just ONE day...and I know i'm not that big or anything but my goal is really just to be a healthier person.
So.. Heres my first incredibly embarrassing photo.. I wish I had a shot of tequila to press the post button...

This will be especially interesting seeing how ALL my friends, and family can see this....
