disordered eating & eating disorder are not the same....but disordered eating can turn into an ED......so it's best to get professional help....sounds like you need some help understanding WHY you are behaving in this way & only a professional can help......

Most ED's have a much deeper issue underlying them than just wanting to be thin & loose weight & if those things aren't addressed, the ED can never be resolved, only managed.

Definitely talk with a specialist.....I don't always suggest ED specialists because some of them only think on body image issues as being involved....someone who can handle deeper issues is usually more helpful but some ED specialists aren't so superficial,,,,,,helps to look for one who will give you the help you need even if you are only doing the disordered eating thing.
