Bummer. :-(
Speaking of autoimmune disorders: [link|http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=9256593&dopt=Abstract|Study indicates anorexia may be an autoimmune disorder]. [edit:] And [link|http://z.iwethey.org/forums/render/content/show?contentid=232619|this] story from The Economist.[/edit]
It would be nice if our bodies weren't so complicated and we were able to say that X is caused by Y and can be fixed by Z. We have a need to find solutions like that (that's one reason why quackery is so popular).
I assume you've investigated things like food alergies too? Maybe you need to go on an all baby seal diet or something... ;-) I'm only half kidding. Diet can have a pretty big impact on the way our bodies work (e.g. [link|http://www.epilepsy.org.uk/info/ketogenic.html|high fat diets] are claimed to help some types of epilepsy).
Hang in there. Medical science marches on pretty quickly these days. With luck they'll find something that helps soon.
Cheers,
Scott.
