I feel ugly

If I could change something in myself, I would change the way I look. I would change my weight. I feel like a very fat person. I don't like myself. I never say it because it's not something I'm proud of. But I have reached the point in which I need to make my decision of losing weight public so I can actually stick to it. I have told my roommates. And now I post it here. This is so embarrassing. But let's face it if I don't like myself, nobody ever will.
