I'm an anorexic who enjoys watching fat people eat
Why do you like watching that?
It's fun to watch their unhealthy face when they eat
It's not mentally healthy for you to watch fat people eat, and it's not physically healthy for you to be an anorexic.  If you want to get healthy and not start to develop mental and physical issues, you should stop doing both of these things.
I like the way they inhale the food, they also enjoy eating so I don't really feel bad. It's not like I'm forcing them to eat or being cruel.
I know you think you're not hurting anyone, but you're hurting yourself. I think you time would be better spent on fixing your own anorexia, than watching fat people eat.
