Oh God, NOW I Feel Thin

I've been eating nothing but light popcorn for months and still looked like a huge cow every time I saw myself in the mirror. I buried my disgusting body in sweats and wraps to hide my globs of fat as best I could. Finally I got thin enough to get out here in public, but now in the bright sunshine, I look waaaaay too thin. Maybe the lighting in my room is just bad? Is my mirror broken? Oh for fuck's sake, you can see inside my bikini bottom I'm so skinny.
