What should I do? I struggle with anorexia but spend lots of time looking at and enjoying pictures of overweight people.
Why do you enjoy looking at pictures of overweight people?
I'd love to watch and look at them, it sounds fun.
That is interesting.  It is probably a good thing to seek help when you suffer from an eating disorder.
I'd love to talk about my eating disorder with you. Your name?
Seeking treatment from a professional for your disorder is wise. They would be able to help you understand why you have developed the disorder and what you can do about it.
