I'm sixteen and I've always been a little bigger than most girls. Now that I'm in high school, there's a lot more pressure on having a great body. I've been noticing for the past few months that I'm a lot more overweight than I thought. It just crept up on me. I really want to be at least 150 by Christmas. That was my weight in eighth grade. Apparently, it takes no time at all to gain 25 pounds. I'm following through this time. Keep me in check?
