Smiths, can I just say that first up - you're not any less deserving or severe a case than any other individual on here. That might seem like a very patronising statement but it's true. The reason? Most ED behaviours don't exhibit themselves as predominantly food-related. Sounds weird, but it's true.
The food thing in the majority of cases comes from phobia, strict control, compulsions and habitual mannerisms where food just happens to be part and parcel of the entire gig.
For example, my own ED was formed through a lack of long-term ambition (I'd achieved all my goals, and as such my ambitions fell by the wayside and I started executing a set of "Daily goals" based on arbitrary, numerical compulsions). It was all about "beating my numbers". Food just happened to become involved to the point where I was restricting an insane amount and performing an obscene amount of repetitive (and in hindsight, fairly ineffective) rep-based exercises, beating what I did the previous day, just to feel a sense of achievement.
Perhaps you too have endured an overachiever's lifestyle and have suddenly faced a void that these OCD behaviours now fill?
