Body dismorphia is wild, because when I was a teenager I thought I was fat. I literally saw myself fat when I looked in the mirror. I did not notice my weight gain, physically. I was puzzled why I needed bigger pants. "I look the same...what the fuck?" When I actually got fat, the person in the mirror did not change at all. It wasn't until I saw pictures of myself when I was thin that I finally realized I'd been experiencing body dismorphia the entire time.
