Absolutely, Amy. It sounds like you're dealing more with inherited chronic disease, something I'll have more on in the near future. The best is to hire a qualified vet homeopath to guide her to cure. You've mentioned using "homeopathy," but I'm not convinced you had good prescribing done by a professional, or you wouldn't still be in such a muck hole.
I describe how to find a likely vet to help you in the report Apoquel Alternatives. Scroll back up to the shaded box just at the end of this article and it'll tell you how to get that accomplished. Bottom line: this is curable. And, it'll take a trained professional to guide the course to cure.
