The Problem with Skinny, By a "Twig"

*Disclaimer Time* Before I start in on this, I want to make it clear that here, I am discussing problems I have had because I am skinny. A lot of these problems come from the glorification of thin-ness, the same place as other, more threatening problems than mine. This does not make my problems more serious than others, but it does not invalidate them either.
I had been thinking about writing this for a while, and recently I came across this video which helped me get around to it.
I have been skinny my entire life. As early as elementary school I can remember being told that I could be a model. That didn't seem right to me. I was told I could be a model more than I was told I could be a scientist. I was being told (in elementary school) that my weight was more important for a career choice than my intellect, mostly because I was a girl. The thing is, I couldn't be a model. Besides my uneasiness at promoting a franchise that makes people I love uncomfortable with their own bodies, I twitch when I put on makeup, I wouldn't be comfortable in some things, high heels would kill me, and I wouldn't be willing to ensure that my body continues to conform to waist-measurement standards.
When I was in middle school, the doctor decided that I was underweight and needed to make some changes to my diet in order to gain weight. I had not gotten to that point by starving myself, I had gotten there by eating relatively healthy food and minimal exercise (muscle weighs more than fat so...). I was skinny, I was not healthy. I started drinking 2% milk and I was finally weighing in over 100lb.
I have had people joke about how my parents starve me, how I have a hollow leg, how I'm skin and bones, how I weigh like 20lb. I have learned to brush them off, especially from friends. I have seen an organization that is supposed to focus on promoting health rather than appearance post a picture of a girl from a magazine and ask "is this a healthy image to be showing girls?" The comments flooded with "she looks sick," "somebody get this girl a hamburger." I thought she looked like me when I'm a little tired. I get self-conscious in my Karate class because the uniform shows off my collarbones but it's obvious by my push-ups that I don't work off my food on a regular basis. Do they think I throw it all up? I don't. That's right, the twig feels uncomfortable too.
If you feel like you need to be shaped a certain way, allow me to throw you a few reasons starving yourself is not worth it. You might not have heard some of them before, and even if you have, here's me affirming them:

• Clothes will not fit you. It may be hard for you to find clothes that fit you right, and it's hard for me too. I am shaped like a mannequin, but they don't make clothes for the mannequins. They make clothes for more common body shapes, and pin the clothes on the mannequins to make them look better. So yeah, they push for a certain body shape, but don't actually make clothes for that body shape. (actually, the stores that actually sell clothes that might fit me tend to be the kind of company that burns out of season clothes rather than donating them)
• It will not make everything better. I have been skinny my whole life, but I have not been popular. I have only had one boyfriend (and it's debatable whether that one really counts?) and generally not the girl the guys fight over. Thinness is not a magic solution to social problems, no matter how often people pretend that weight is what pushes people out.
• You will always have something to pick at. Even if you can completely change your body type, there will always be that thing that stands between you and perfection. Me, I feel like I have a mountain range on my forehead (which I have been told no one notices), and funny-shaped thighs (which have never been commented on). That insecurity is never going to be gone.
