When I was 16, I was 5'8"(still am) and 110 pounds. Way too skinny...but I ate all the time and never worked out. Then good ol' metabolism caught up with me and now I'm 135. It's a good weight for me. But at times I do feel like a heifer just because 25 pounds in 5 years is a lot. But I was way too thin in H.S. I'm pretty comfortable with how much I weigh now, but I do really need to exercise just to tone up not necessarily to lose weight.
I think that every girl/woman has some sort of body issues just because of the media and how they push the idea that if you wear over a size 6 you should just crawl into a hole and die. Thankfully though, most of the women are smart enough to see that this is major b.s. and have learned that they're perfect the way they are and to love themselves (for the most part at least
).
