Seeing as we are not medical professionals here, we cannot diagnose you with an eating disorder or anything else for that matter. IMHO it sounds like disordered eating, but that is my opinion. Probably the best place for you to start to get help is at you GP's office and be honest with them. Print out this post and show it to them. Get help before it is too late and your children have no one to care for them. Again, this is only my opinion.
