Yes. I have been what most professionals would consider 'morbidly obese' for the last fourteen years or so, but back in my teens when I was in my hardcore yo-yo phase and when my bulimia started I got really thin and couldn't relate to my own body anymore. And I did end up having my first massive episode of dissociation/panic/agoraphobia at that time. So yeah. Totally relate. And it sucks.
