I hate it when my sister brings up the topic again. Every single day of my life all about weight&diet. I seemed to get damn annoyed already. This makes me want to eat nothing at all. Especially, my aunt is constantly checking on us. She's actually very critical as if!. I am starting to hate her. I swear and I really want to be determined right on that no matter what. I will be the skinniest.

She should watch out for that.
