Eating Disorders- A Different View

Have we ever thought of Miss Havisham being over weight here is another view and a different take on viewing the lonely woman. It could work, she is wealthy so can afford plenty of food compared to Pip. She could comfort eat, just sitting there eating to fill the hole her Fiancée left, she also never gets up and walks so it could all make sense. Maybe this would be depicted in a American modern version. A very over weight woman who just sits and eats. 

Or would she have a different kind of eating disorder, would she have had anorexia or bulimia? Eating her wedding cake and then throwing it back up or would she have just given up eating entirely and given up on life being a tiny skeleton.
