I dont like my body

And yes..this is one of those typicals days when i dont feel comfortable with my body
I know people grow up and body changes.You can get fat or loose weight,you know.
I hate the simple idea that im getting fatter and fatter everyday.I HATE this feeling.
I dont wanna feel this bad u.u

I also understand that im not that fifteen years-old girl and my life changed,but idk..
i just wish i could get thin ,at least,i wanna loose some weight.I will feel very happy that day..

I wanna be myself...but feeling this way,it doesnt help
