lose five stone - get to 11 stone

I think I am currently about 16 stone, which makes me feel really shit and ugly. I am a fashion student and it upsets me that I cannot get as into fashion in my own way as other student because I just dont have the confidence (or the body) to pull things off like other people can. I know that some people say that every size is beautiful or some crap like that, but it is so untrue in the field I have chosen to work in. It can affect what jobs you get and how the whole world around you sees you. So to help me do this, I am going to start a food diary. :)
