I know.  I hate how judgmental people can be.  I'm one of those annoying girls who claims to have "too much fat", and yet still indulges in chocolate every day X).  

It really sucks that I'm a teen and millions of other girls are still so perfectly skinny, like they could fit into everything.  I figure it's mostly because of their metabolisms, or just being very active growing up. Somehow they can have flat stomachs and great legs effortlessly that I would have to really work to have.  

I really hate how the media and people automatically think you must look a certain way to be beautiful.  What's nice to remember though, is that some people(not as common as most humans, but they still exist) don't draw conclusions and opinions of someone based on their natural appearances, but rather, they're individuality, which is (in my opinion) a more interesting form of beauty.  

Above all, remember that you're not alone; many girls feel the same way, and always hold your head high.  Some guys find confident, outgoing girls with decent looks more attractive than a gorgeous girl with an awful personality and character.  Again, not all of them are like that, but they still exist ;)  

And before I forget, don't spend all your time worrying about what other people will think of you, but rather, focus on making good choices that will mount up your character.  Get involved with something you love, whether it be an art, sports, community service...  

And for finding cute clothes, don't underestimate the awesomeness of thrift stores! xD  I honestly get a lot of my clothes from them, and you can find lots of cute stuff.  There might be a teen thrift store, "Plato's Closet" near where you live.  If so, go check it out.  They have great selections and lots of sizes.

Anyway, sorry this is so long.  Believe in yourself, focus on your good qualities, and strive to improve them.  If you do that, you should eventually become an amazing person to others, regardless of your weight or whatever else you think they're judging :)
