Unfair

All my life I gave been made fun of for being fat, this summer of 2013 i tried to lose 10 KGs ,but i ended up losing 2. I had to lose 10 to be more secure, but I failed so a few minutes ago i could handle it and I started to cry and blame myself for not continuing. During my breakdown i went to my best friend and like always he cheered me up quickly. The reason of why its unfair is, because people made fun of me the whole school year, they kept telling me I was pregnant or, I should wear a bra so I decided to try to lose weight and this whole summer before i go on my vacation on August 6th I have been trying to lose weight but i ended up failing and disappointed. God why did you make people that are rude? and, why do people treat you badly if you have never done anything to them? I hope I lose a lot of weight in September so no one can call me rude thing anymore.
