text: weight for teens? i know this might sound stupid but, i am 13 years old, 5'3" weighing 100. i have a flat stomach for the most part but need to work on my abs... but i feel like i'm getting fat around some of the girls around me! i dont have an eating disorder or anything but should i just keep working at it? what should i do? i dont like feeling this way!...please help, serious answers only. i know that in the culture that we live in it is a huge temptation to strive for perfection. you are 13 years old and it sounds like you want to take care of yourself and be healthy.  if you are eating lots of fruits, vegetables and whole grain breads and drinking lots of water and adding in some exercise a few times a week you are off to a great start.  don't worry so much about what the scale says or what size pants your in...if you feel good and energetic and your having fun with your friends that is what matters.  you are not at all fat and i think it would be great to know that you are having fun in life with yourself and your friends. just be you and enjoy everything life has to offer that's what matters most in life in the end.
