I'm 5'6.5 and 136 - the heaviest I've ever been. I don't think I'm fat but I always feel like crap when I look at my tummy. I weighed 100 pounds last year, I was quite underweight and then I just went up. I know I'm not overweight but it's just tough for me, I'm almost fifteen and it's just sort of miserable being a teenager. I want to lose anywhere from 6-11 pounds and work on my stomach.

Ana, your weight is perfect! If you lost 14 pounds, you would be bordering underweight (all that according to the BMI chart in my mom's office...). Ultimately it's your body and your choice, I'm not trying to nag.
